$(UWe are running Suse10SP1 OES2 GW8

2-3 times a day, random times, the webaccess agent stops communicating and we need to restart webac80.

I can find nothing in the logs, (have it on Diagnostic) If I'm luck and have a terminal window open I can see some of what looks like a memory dump referencing many lib's.

I know this is very vague but I need some direction on where to start to look.

Thanks in advance
