I have a group of Netware 6.5 SP5 servers pretty basic all configured the
same and I am getting Cache allocation errors.
When I review the server resources the file cache is down to the teens and
the VM free clean is using well over 50% of the memory
Is this memory to be returned to the file cache after the VM is done with it
or do I not understand the what free clean VM memory is. After a reboot the
system looks fine. We are not running any backup software on these servers,
but are using rsync to sync data to a backup server.

Any insight would be appreciated.
I have included a copy of the segstats.txt
