we have a netware 6.5 sp6 server that is leaking memory -
at this stage ive had about enough of it so here is the segstat
from it and if anyone can shed any light on it it would be great and i
also hope i'am posting into the correct group, in the last 2 days
available logical space has droped from 820 mb to 595 mb, we had issues
before with memory leaks but thought they were all addressed with
Service patches.The memory leak seems to have started since loading
Advantage Database server [Sybase] - has anyone has any such problems.
We had the same problem on another server but edited the CFG
file for advantage to limit its cache to 300mb and it stablised it, but
the same setting on this server seems to make no difference -
which is why i'am now looking to anyone for help
Thanks
Michael
