Cant use Classic since migrating my catalogue to CC. Keeps crashing.

  • Updated 5 months ago
All was working fine until a few days ago. I decided to up my storage quota and add all my images from the past two years to Creative Cloud, via Lightroom CC. All went well and both CC and mobile are working fine.
Today i opened LR Classic (my main program for working in) and it started to sync 1000’s of photos. I’m not sure where or why, but I’m guessing its syncing back in the photos in the mirgrated catalogue (which is already in Classic).
Anyway, Classic keeps crashing and never gets anywhere near completed. Ive turned off syncing for all the collections but still its doing it. I wouldn’t mind but its causing Classic to crash and when i re start it I’m back at the start. It’s an endless loop that now means Classic is unusable for anything.
Things are really gong downhill and i can understand why there are so many posts from people going elsewhere. I will too by the end of next year. I want to edit photos, not be constantly re configuring my computers.

Exactly. If you have LIghtroom CC and Lightroom Classic CC logged into the the same Adobe ID anything in Lightroom CC will sync down to Lightroom Classic CC.  If you don't want this to happen, turn off sync in Lightroom Classic CC.

I still want LR mobile to sync to Classic, as i need to change the camera profile in Classic on some shots. Am i to assume its either none or the full lot now?
Everything other than a collection called Lightroom mobile (which is my ipad) is turned off for syncing. LR mobile has 288 photos in it, yet Classic is trying to sync over 5000 raw files, and crashing in the process.
All i want is the 65 photos i took over Christmas to appear in Classic. So far after 2 days i have 8. The rest are pending and stuck within the 5000 image LR is insisting on syncing., but not being able to do.
I’ve had to remove two folders from my Classic Catalouge that had over 3000 images in it, just to get the numbers down to 5000. I really cant remove everything .

This is a bloody mess.

You either sync down all or don't sync down all. There is no partial sync down to Classic from the cloud. 
Syncing up to the cloud from Classic is partial and controlled by choosing which collection(s) to sync.

Well i want all my new files (from my ipad) to be in Classic. It’s been working fine for months until i migrated my Catalogue. When that happened i got all my images appear in the cloud, it took a few days, and i can see them on my other divices. Nothing new has been added to Classic directly, and ive only taken 65 or so new images since the migration process was completed.

So what is it that Classic is uploading? Nothing is set to upload, i cant even see anything to turn off for this feature other than to pause overal sync, and everything its uploading is already in the cloud.
And of course Classic isnt up to the job of uploading all these files anyway, so it crashes.

Again, its a bloody mess.

I understood from your earlier comments that Lightroom Classic CC is downloading from Lightroom CC. Now, you are telling us it is uploading as well. 

You can review what is syncing either way by going to the Preferences>Lightroom Sync and the panel on the bottom will give you a breakdown of what is syncing. 

If you don't want to sync down the Lightroom CC info and still want to ingest your iPad images, you best option is to turn off sync in Lightroom Classic CC and then download the iPad photos via your cable connection/import method.

Ok, let me try and explain what I’m seeing.
In Lightroom CC i opted to migrate my Lightroom Classic catalouge. LR CC did this and took about 2 days to upload the raw files. That all went well and i can see them on my ipad/iphone as smart previews.

A few days ago i opened up LR Classic, and it said it was syncing a few 1000 images. There were many waiting to upload, many waiting to download and many that just said pending.

I turned off all the collections that were set to sync, expect for my Christmas one (which has only just finished downloading to Classic)

At the top left hand corner LR CLassic is telling me its syncing XXXX number of images, but double clicking of this opens the Cloud window thats shows many, many more images are being or waiting to be synced.

The issue i have is LR Classic will crash randomly while its doing this. Sometimes every few min, sometimes a bit longer . I’m not using my PC for anything else and still it crashes. Sometimes it causes my PC to crash and needing a re boot. This has been going of for a few days now and i cant use my PC as LR CLassic is hogging all the memory (16GB installed). No other large programs will open, and even LR Classic is telling me I’m running out of Ram.

Why on earth is Classic uploading anything? LR CC has already done this. I can confirm that everything from the catalouge has been uploaded to the cloud already, yet Classic seems to be also uploading the whole catalogue again, and crashing in the process. Other than turning sync off completely i can see no way to stop Classic uploading anyway.

Suggesting i turn off Cloud syncing is a work around that really defeats the whole idea of being able to edit my images on any device. I’m paying for a cloud service, yet i need to turn it off to get any work done.

I have the same problem and also a lot of sync failures. I have tryed many things, but nothing works.
Adobe must fix it quickly, because it is not ok and takes a lot of time with no work done :(

They wont fix it, and if they did the fix would be months away.
Since my last post I’ve now noticed LR Classic is just closing itself down after a few mins. No error messages, just closing down.
At this rate ill have a working Classic at ther same time I cancel my Adobe subscription next year.

It’s really not funny how a company this big can cock it up so badly.

Reading your description, Dave, I gather - as long as Lightroom Classic is not involved, Lightroom CC (Desktop and Mobile) are functioning fine, syncing properly and not crashing, correct?

If you leave LIghtroom Classic off,  Lightroom CC will eventually finish syncing and show "Synced and Backed Up" when you click the Cloud Icon in the upper right?

At this point, if you launch Lightroom CC for mobile on your device and leave it to sync, eventually will it show "All synced and backed up" when you tap the Cloud Icon in the upper right of the mobile app?

If the answer to those two is "yes" then this is how I would proceed. 

Close Lightroom CC.
Launch Lightroom Classic CC
Pause Syncing immediately.
Carefully scrub your Collections panel and locate any and all collections that have a Sync Icon showing. Some of these may be nested deeply inside collection sets depend upon your organization.  Once you are satisfied you've turned off syncing on them all.  Close Lightroom Classic CC.
Restart your computer.
Open Lightroom Classic CC
Turn back on Syncing. 
At this point the only thing syncing should be your files coming in from the cloud which will be a collection of:
1. Photos from mobile apps.
2. Files you've imported directly into Lightroom CC.
3. All files you migrated during your catalog migration. 

If you are still seeing files attempting to upload from your Lightroom Classic CC to the cloud at this point, I would consider going with the nuclear option of killing the Lightroom sync file for Classic and letting it start over from scratch.  If you decide you want to do this, the file is located typically at C:\Users\<user>\AppData\Local\Adobe\Lightroom\Caches\Sync Data\Sync.lrdata 

This will start all syncing over from scratch on your LIghtroom Classic CC side.

Note: none of this addresses the crashing behavior. I am just trying to isolate why you are seeing two way sync from Lightroom Classic CC when you should only be seeing download sync. 

My goal is to get everything synced down before you attempt to sync up...

Thanks for the reply.
I’m traveling at the moment so excuse any errors in my post, but this is what’s going as from this morning, from memory.

First off, Lightroom CC and mobile are working perfectly. Ive added a lot of raw files to CC today and they all synced fine with mobile and Lightroom web.

It’s Classic thats causing the issues.
First off, Classic was working fine before i migrated the catalouge. Classic would sync my mobile devices fine, withoutout any issues. I would load raw files to my ipad, import them in to LR CC mobile, and this si turn would send them to Classic on my PC. This is still the case, but its the main part of the catalouge that seems to be the issue.
For some reason when i opened Classic, after the migration and a few days after all the images had uploaded to the Cloud it wanted to upload a few 1000 images., and download a load. This is strange and i had already migrated this catalouge and according to LR CC all 8,000 images had uploaded to the Cloud already, and no new images other than the 60+ i shot over Christmas were added to any catalogue. These have finally come through but still Classic is saying there are about 20 more photos still neededing to sync.

The Syncing part is not a big deal IF Classic wasn’t continuous ly crashing. It started off with a Crash Windows popping up every now and then, asking if i wanted to send info to Adobe, but over the past couple of days Classic is just shutting down. No warning or error messages, its just not open anymore. I might get maybe 2 or 3 images synced before this happens again. This could be 2mins or 20mins. However long this period is its only syncing one or two images before crashing, and it seems once i restart Classic after a crash it’s back to the higher number again.

Ive cleared out all missing files, and any files that had errors. There were a lot of error showing from files that are not missing and have nothing wrong with them. These were uploaded to the cloud fine using LR CC.

I see no way of stopping any uploading, and the files that are uploading are already uploaded via LR CC. These have not been added since i migrated the catalouge.
All collections have sync turned off other than one that says LR Mobile. This is the only collection i really want to sync.
I want to use Classic as i used to, with access to files loaded on to my ipad, so cant turn off syncing completely.

I did delete the sync.lrdata file last night, as i had other issues, and the new file did quickly whizz through and get back down to a small number of files still syncing, but it looks like it will be another day or so before the last 20 files are sysnced, if thats even the end of it.
For the record i have a very fast fibre optic connection so speed at my end is not an issue.

Right. All the uploads have completed and I have 5 downloads stuck. Minor issue although these are stuck on the Adobe servers so I see no reason why they wont download. Just tested my internet speed and its averaging 15MB/s. No errors are showing. I am getting a sync between LR CC and mobile.

I’m now stuck with LR Classic still crashing randomly. I’m not even doing anything with it, i just leave it sitting there and within 10mins its closed itself down.
I don’t have GPU enabled, and have reinstalled the most up to date graphic drivers, just in case.

No other programs are running , except the usual AV etc. Nothing new has been installed on this PC for ages.

re: the 5 downloads that are pending: 

1. How long has it been since the number has been stuck at 5?
2. Are you able to determine which images/vids are stuck? (the Preferences - Lightroom Sync ) panel should tell you which are left) What type of files are they?  Where are they coming from (Lightroom CC,? iPad?)

re: Crashing
How many crashes do you see in an hour? Day?  Is there any behavior that you can perform that makes it crash consistently? Have you been sending in the crash logs when it crashes? Any other error messages?

The 5 that are struck, and have been for about 24 hours, seem to be videos. Ive just checked them with Lightroom Web. They must have got uploaded through LR CC. I don’t need them so I will delete them.

Regarding the crashing. It’s ranodm but I’m not actually doing anything with LR, or my PC. I just open LR CLassic and let it sit there. Within 10mins the screen goes black, Classic shuts itself down and I’m back to the desktop. No error merssages at all. As I said above, I have been sending the crash reports until that window stopped showing up.

One thing I noticed. If I turn off Syncing Classic stays up for a lot longer. In fact I’m just testing it now to see if it makes a difference. I think it does.

I sent a message to SatishT - an engineer on the product - he was reviewing crash reports in another thread. I've asked him to take a look at yours.

Thanks Rikk.
Ive deleted those 5 files and now Classic seems to be stable as its finished all its syncing. I have had to remove a lot of files so I now have a smaller catalogue than CC has. Using CC was just to see what it was doing, I really need to use Classic as my main editor. It seems to be syncing ok with small edits.

It’s very frustrating though that Classic is having all these issues, yet LR CC is rock solid and handles these same files fine. Ive still got around 25+ video files, same format, some a lot larger than the 5 I just deleted in the catalogue and Classic is fine with these. In fact these were all in the catalogue before I Migrated it.

To me the issue is how Classic is handeling the syncing, and this is the cause of the crash. I think I saw an error about out of memory a few times over the weekend., and the black screen would also point to a memory issue. I did run the Windows Process tool but couldn’t sit and watch it for too long. It did seem like the memory allocation for Classic was creeping up, even without use. In the past its been fine when just syncing to my mobile devices.

Is there a FAQ about how the catalogue works once its Migrated? I get the feeling Classic was downloading files that were in the Cloud, even though it had them already. That’s just an observation and I could be wrong, but what else would cause it to sync its catalogue with CC’s, and download and upload so many files, when both have the same images in them.
