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.

    sync with mobile is off.  here are some ips: 52.202.115.220, 52.207.10.7, 52.0.43.175... all port 443.  I tried resetting prefs, but still exhibits the same behavior.

    Do you have "Sync with Lightroom mobile" enabled? It looks like it because you mentioned Amazon cloud servers. You mentioned that you are running a perpetual license copy of Lightroom. The Lightroom mobile sync should not be even enabled. Can you tell which Amazon url that Lightroom tries to connect to?

    Can you also try to reset your Lightroom preferences (holding down Shift+Alt when Lr is launching) to see if it helps.

    As far as I can tell, Lightroom is idle. I haven't done any extensive instrumentation, but have looked at the running threads under process explorer and (to me at least) they just look like standard maintenance threads that are running.

    I upgraded 9 days ago so I could start working with RAW with my new 7d. I was running with 16GB and memory was tight, so I upgraded to 32GB. Imagine my surprise to find the thing swapping! 

    This catalog has roughly 65k pix with both the catalog and images stored on a 3T RAID array. 

    When I first open light room, I can watch the memory usage start to creep up from initially around 500MB to 2GB in the first 5-10 minutes. It just keeps going.

    The only thing I have noticed is my firewall reporting Lightroom continually trying to open SSL (port 443) connections to various Amazon's cloud servers using incrementally increasing outgoing ports.

    I will try to do so more digging as I get some spare time. Right now, import another 600 photos from a shoot I did this morning.

    Any idea what Lightroom might have been doing at the time? I have a sync related suspected massive leak, just on initial sync.

    Roughly how long ago did you upgrade (i.e. few hours vs few days?)

    Roughly how many pics in the catalog? And where are the images stored? On the 8TB drive?
