P: Memory Leak

I just left LR idle for a few hours and came back to find my 32GB machine 100% memory with 100% disk due to paging with Lightroom being the culprit.

If I open up System Info from the Preferences->Performance->Camera RAW section, I can watch the "Real memory used by Lightroom" increasing continuously while LR is idle.

Background:

Just upgraded to standalone 6.8. Was previously using LR4 with no problems, but needed new camera RAW support.

I built this machine myself and it has been rock solid and a great performer for 2 years. I use it for software development running linux in a virtual machine to do heavy multi-core compilation and to run compute intensive multi-threaded/multi-core applications for IC design. Never a problem.

OS: Win7 Pro

CPU: Quad core i5-3570

MB: Asus p8z77-v pro

Disk: 8TB configured as a 3T RAID5 array, 4T standalone and 256G SSD

Memory: 16GB just upgraded to 32GB.

    Had this issue with previous version and now with the CC2015.9 version as well.  Totally unacceptable that Adobe releases revisions that continue to render their products unusable.   I get about 3 minutes of use in LR before every byte of VM is burned.  Not fixed and not usable.

    I can confirm that clearing the video cache seems to have fixed the problem. I'll continue to monitor.

    Thanks. I think I found the memory leak that you both run into and it will be fixed in the next Lightroom update.

    Also are you running some 3rd party Lightroom plug-ins. I saw some Dropbox extension code loaded. Try disable the plug-ins to see if it makes a difference for you.

    Can you try to clean Lightroom's video cache folders: 

    In Windows Explorer, navigate to the two folders “C:\Users\your account\AppData\Roaming\Adobe\Common\“ and “C:\Users\your account\AppData\Local\Adobe\Lightroom\Caches\Video” and just delete both folders? Then restart Lightroom.

    Any video cache files that are needed will be regenerated when requested.

    Just to make sure that you were not doing any thing inside Lr during idle? Can you tell the time duration between all those peaks in GPU usage?

    Been really busy with a musical production, so haven't had time to followup on this, but just wanted to add a few new observations.

    Two nights ago, I left lightroom open and I was surprised to come back in the morning to find it just fine. Then tonight, I left it running for a few hours and I come back to it swapping again. I was using the same catalog and can't tell you what the difference between these two sessions were. Very odd, but I will try to nail it down.

    I've taken some screenshots as well.

    This just now while it was swapping away. Caught it early enough my system was response enough to grab these.







    And, here's one that shows what was going on the other day as it was slowly working it's way up.



    This was the thread capture just as the process was killed.

    So, without Sync my issue is a slow-burner and I can live with it, 27hrs of just a minimised LR CC and it's got up to a virtual size of 20.5 GB ... much slower grabbing of memory than with Sync when it would max out my system at 40GB. It's up to 13GB (of 16GB) of real ram used, no room left for my virtual system!  There's definitely something wrong, and it's a lot 'more' wrong on Brian's system.
    That's it from me, too much real work to do, I'm shutting down LR and getting the other systems back up. Bye
