LR5.3 hanging problem

  • Updated 5 years ago
After installing LR 5.3 (as a new Lightroom user) I have been keywording my photo collection, typically sets of 10-150 photos at a time. During this process usually first everything goes fine, but after some work has done, LR5.3 gets endless hanging. It blinks same screen endlessly and Windows Task Manager reports "not answer". There is also an AppHang transaction in Windows log file. Well, my PC is not very powerful, AMD Athlon II X4 645 3.1 GHz processor, 4 GB RAM and Windows 7 sp1 64-bit, but I'd been using this computer with Corel's PaintShop X4 with no problems of any kind. I turns to Lightroom beacause of its much better raw photo capabilities. Now I'm little bit disappointed: LR is a fine software but seems unreliable.

I get a consistent 4-second hang after selecting more than one photo. During this time I see no activity from Lightroom.exe (I'm using procmon to see what LR is doing) so it's not hung on I/O. Immediately before and after the hang, I can see LR accessing file handles and the previews DB.

During the hang, the UI is completely unresponsive.

Try running Lightroom with no other applications (including email) open.
Have you optimized the catalog? File > Optimize.
Does this happen with a brand new catalog?
Where are your photos located and your catalog? How much space is open on your drive/s? Make sure Lightroom is opening in 64-bit mode, but looking for X64 in the title when you start it.
Try resetting preferences: http://helpx.adobe.com/lightroom/kb/r...
How large is your previews file - it's with your catalog, has the same name but ends in Previews.lrdata? Unlikely, but it could be damaged. You might want to delete it - it'll rebuild itself, but it'll take time to rebuild previews for each folder you open.
Try running Disk Clean up (Start > Programs > Accessories > System tools > Disk Cleanup, and choose to remove Temp files (these are different from Internet temporary files).

Deleting my preferences fixed the problem. I still have the old prefs file if you want to take a look.

I'll keep an eye on which preference seemed to introduce the problem.

The rest of the items were generally in good shape.
* I optimize the catalog weekly.
* This error happened even when I export everything to a new catalog.
* Catalog is 110k photos; about 100 on local SSD and the rest on NAS connected by gigabit Ethernet. ~100GB free on local SSD.
* Lightroom running x64.
* Cleaning up previews didn't help.
* Disk cleanup didn't help.

Tina, thanks for good suggestions. However, I optimize the catalog regularly (every time I leave LR, in fact). My photos and catalog is on same physical drive but in different partitions. Drive is internally connected and there is about >70 % free space on that physical drive. Only catalog and photo backups are on external drive (USB2.0), so slow USB cannot cause the problem. I also clean up my internal drive weekly. And yes, I am running LR in 64-bit mode.
I have not yet resetted my preferences, but I increased the size of Camera Raw Cache maximum size from 1 GB to 3 GB (preferences | file handling), and my first impression is that this might have been helped. The problem occurs only when I was handling several raw photos at a time (i.e keywording them). I'm hopeful now and looking how it is working. Thanks also to Dan.
