For any of you with your volumes on a fileshare on a server 2008 R2 or earlier...
We were having a problem with the Windows Metafile taking up all available RAM for caching.
I suspect that Laserfiche servers with many volumes on them are especially vulnerable to this particular issue since we have millions of files there.
It seems this is a bug/feature Microsoft knows about : http://support.microsoft.com/kb/976618

Eventually everything will slow down on the server due to lack of resources. Adding lots more RAM didn't seem to help - it would just increase the time it took to fill the RAM.
Anyone else seen this, or just us?
The cache service I linked above seems to be a fix, or at least a band-aid.
