Server: NW 6.5
Patches: SP7 and all post SP7
eDir 8.7.3.9
Arcserve 11.

I have the following segstat.txt for a server. The problem is that it keeps
running out of cache. These stats are taken w/o Arcserve loaded. As soon
as Arcserve loads, the "Total cache buffers" goes down to 85,000, the
NWMKDE.NLM will use 750 MB of RAM, and nothing will run. Any thoughts on
what configuration changes or ideas?
