Asus Z97WS motherboard, Intel i7-4790K (not overclocked), 32GB, 8TB RAID-6 data storage (5TB free)
Since the update to 11 I've been experiencing difficulties if I try to import more than a couple of dozen files at a time. LR becomes unresponsive during the import. Sometimes I can cancel the import by clicking the red X in the progress bar, but usually I have to kill the process with Task Manager and re-launch.
Some data points:
All the files have been copied from the source media, but not all have been added to the catalog
It makes no difference if I import directly from an SD card or first copy the files manually to a temp location on hard disk before importing
After restarting, I can "synchronize": the folder into which I imported to add the "missing" files to the catalog.
Sometimes I'll get a "preview missing" error message for one or more of the recently imported files. I can manually regenerate the Smart Previews.
Is adobe aware of this problem, and is it being addressed?
