Lightroom Desktop: lrcc_console.log file filling my C Drive

When I use Lightroom CC Desktop (Cloud based) for several hours, the lrcc_console.log gets so big that it renders my computer unusable. It goes from 0 to 40GB in about 8 hours if LR is running (I don't have to be actively using it). When I close & reopen LR the file reverts to 0 KB. 
I am using Windows 10, version 1909
Lightroom 3.0, with the most recent update

The log file appears to contain multiple similar error messages - I have included a screenshot of one of those. 

This is the message that appears in LR. My images are stored on the D drive. The only issue is the size of the lrcc_console.log file


This is the size of the file after I left LR running overnight.


Immediately after restarting LR: 


One of the literally thousands of error messages contained in the log file:


I have tried reinstalling Creative Cloud, reinstalling Lightroom, updating Windows 10. I have contacted Adobe support 3 times but they have not understood my problem. I hope someone can help!

Greetings Shelley,

I've had the engineers take a look at your lrcc_console.log file issue.  

Given the nature of the error, they feel the best option is to perform a resync by deleting your local catalog and allowing things to sync back down from the cloud. 
  1. Make sure that all syncs have completed. 
  2. Make sure you have access to good wifi to complete the resync.
  3. Close Lightroom
  4. Locate your MCAT file at location: C:\Users\ALIENWARE\AppData\Local\Adobe\Lightroom CC\Data\guid string id\ Managed Catalog.mcat and rename it to "Managed Catalog.old"
  5. Restart your computer
  6. Launch Lightroom and allow it to resync. 
Does the issue with the growing console log go away?

Thanks Rikk. Sadly it has not gone away. It hasn't finished resyncing yet but the file is up to 32.GB already. I have sent you an email with a copy of the log file (when it was "only" 200MB)

Until you finish syncing and restart Lightroom we won't know. Can you update me after syncing is done and you've restarted?

I have finished the resync. Rebooted, restarted LR a couple of times. Sadly it has not fixed the log file issue. It blew out to 2.5GB so far. When I restart LR it reverts to 0 but starts growing instantly. I have attached a copy of the file so that you can see the error messages it contains. https://www.dropbox.com/s/h54on6r569l9z70/lrcc_console.log?dl=0

The resync did fix another issue, which I mention in case it is related. For months LR on the desktop has been saying it is syncing 5 photos. On all my other devices it says "Synced and backed up". I ignored it because it didn't seem to be affecting anything/ This has been happening for months, while the log file issue has only started in the last few weeks.

Thanks fo the update Shelly. I conferenced with the engineers and they are wondering if you are storing originals on an external device? 

If, in Preferences, you switch back to the default, do you still see the problem?

The originals are stored on my D drive, which is an internal SSD. There isn't room to keep them on the C drive.

Lightroom has been running now for about 10 hours and the log file is "only" 10GB. Previously it was up to 40GB and completely filling the C drive so the resync has slowed things somehow.

The C drive is small (256GB), and my LR originals folder is 863GB

PS I assume it's OK to delete the old catalog file now? I don't know if this helps but I noticed the new one is way smaller

If you are confident things are all there the MCAT file you renamed can be discarded.

I couldn't move the originals folder, but I did try unselecting Save Originals, but that didn't help.

Thanks for reporting back Shelly. Have your reset the app preferences yet?

A Preference File will survive a Lightroom uninstall/reinstall. Sometimes weird behavior is corrected/cured by resetting the preferences.

Reset Procedure:
1. Close Lightroom.
2. Hold down [Alt/Opt]+[Shift] while restarting Lightroom.
3. Overwrite the Preferences when prompted by the dialog.
4. Close Lightroom.
5. Restart Lightroom.

Does the issue continue after resetting the preferences?

Hey Rikk,

Sorry to take so long to get back to you. I've had some family stuff and haven't been back to LR. Anyway, because it has been so long, I repeated everything you suggested above and (fingers crossed) it seems to have worked this time! 
Thank you!!

Aargghhh! No - I spoke too soon. It was perfect - the log file was empty and stayed that way for a while. Then the only change I made was to reconfigure the preferences (minor changes - set font to 150% and panel tracks to manual) and the log file started growing again, within 2 hours it was 4GB in size. 

I tried resetting the preferences again but that made no difference. 

Also - it is now saying "Syncing 2 photos" continually, even though mobile and web versions are indicating all files are fully synced. 

AND - after restarting LR, the default font is resetting itself to 150%, even though it had reverted to 100% after resetting the preferences. I didn't change any preferences meanwhile.

At this time, I don't have a fix recommendation for you. The next release of Desktop software will have a fix that should make this go away for you but it will be few weeks yet. I don't have an exact ETA to share.

So I have a second laptop which also has Lightroom running. I haven't used it for months but it occurred to me to see if the same issue was occurring there. And indeed it is - the lrcc console log file is big and getting bigger as long as LR is running. This seems to indicate that this is a LR issue rather than any specific conflict on my system, doesn't it?

Not necessarily.  So far, you still the sole reporter of this issue and I cannot replicate it. That it happens on two of your machines may be an indicator of an issue in Lightroom but it may also be a software interaction with a piece of software or configuration unique to you. In any case we are releasing a change that should keep rogue console.log under control - even if we can't identify the trigger in your case.

Interesting. I don't think there's anything unusual on my computers. But I will stop pestering you and wait patiently for the update. Thanks!
