I have an instance of Zimbra OS Edition version 4.5.10_GA_1575 running on Ubuntu 6.06.1. This instance is running on a VM instance that is a P3 1Ghz with 1 GB of RAM.

I migrated this instance from iron that was running an unsupported version of Ubuntu (7.04). I restored this instance from backup using the various how-tos. It was working fine for a while and then all of a sudden started randomly stopping. I am new to Zimbra, so what logs should I send to help identify what might be causing the random stops? Finally, I had a thought that if this persists I would export my users, remove Zimbra, install from scratch and import the users.

Any help would be appreciated. Thanks!
