We've patched about 10 of our Netware 6.5 servers to SP7. Shortly
after --- 2 servers started having cache memory issues.

Server "Enterprise" 6.5 sp7 (IBM Server)
* 2 gb of ram
* r/w replica
* imanager, norm
* tsm client (5.4)
* netshield (4.63e)
* mrtgext (1.46)

Server SS 6.5 sp7 (HP Proliant Server)
* 2 gb of ram
* no replica
* imanager, norm
* tsm client (5.4)
* netshield (4.63e)
* mrtgext (1.46)

What seems to happen is that the server(s) run fines for 1-10 days after a
restart, then cache memory errors start showing up on the system console.
The errors coincide with the same time Mcafee would be attempting to update
dat files.

Netshield.nlm is at the latest version (to my knowledge software
4.63e/engine 5.3.00). Once this starts happening --- Mcafee fails to update
dat files and every attempt to update them will result in another "cache
memory allocator" error. The only fix is to reboot the server --- then
things work fine again for 1-10 days before the process repeats.

We thought we'd post to see if anyone has any ideas as we've not had much
success in resolving the problem and we didn't have this issue until we
moved to sp7. ... Although we updated to Sp7 and Netshield 4.63e at the
same time. :(

Below are the messages from the system console and segstats.txt from the
server Enterprise if its at all helpful. As of right now, this server is
currently having the issue. We're going to reboot this server tonight.


Thank you for any assistance, clues, or insights.....
