I am getting cache memory allocator out of available memory every day staring at 3:09AM see log. I have a backup job that unload sophos and reload it backup when the backup job is done. That happen around 12:00AM to 1:13AM. I have check my cron job and nothing run at 3:00AM. I have Netware v6.5 SP 5 -CPR Release.
What else should I be looking at the see what is running at 3:09AM that is causing this error?
