[SOLVED] Zimbra Daemons die randomly

[AnubisEnglas]

Sorry if this is a duplicate thread (I have run a search), but having a huge problem with ZCS 64-bit 6.04. Every so often, the daemons will just kick out and Zimbra will need to restarted. The error logs show nothing useful, but there have in the past been stack traces from Tomcat that I can't seem to find at the moment, though I fail to see how this would bring down postfix as well. Has there been any other cases of things like this? All it takes to fix it is a simple zmcontrol restart, but it is rather annoying having to do this every couple of days after having Zimbra running sweet for the last year

EDIT: Nevermind, nothing was wrong software wise. Our UPS completely died today, so it's a good chance that was the only problem
