    Memory Leak when importing

    Jim Garrison Level 1

      Lightroom 6.4 on Win 7SP1 64 bit with 16GB memory

       

      I imported about 1000 Canon .cr2 raw images.  After the import completed, as I was starting to view the images (and LR was building previews) I got out-of-memory error messages from a couple of other apps.  Examining the situation with SysInternals Process Explorer I found that LR was using 12GB and the system was out of memory.

       

      I closed and reopened LR. It started with about 2GB but as it continued to build previews for the newly imported raw images it quickly climbed up to about 6GB and stayed there.

       

      After it had finished building previews I restarted LR again, and this time it stayed at 2GB.

       

      So it seems there is a memory leak during the preview-build process.
