Lightroom 6.8: 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.


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.
