I'm not sure why I keep getting the MTA and Mailbox services dieing periodically on one of my servers. I've looked at a couple of other posts that look like the same or similar issue and didn't get much out of them. Seems like it dies around 11:45 at nite on a fairly regular basis. I found an error in the logs awhile back and thought it was the root of the problem, but still seems to be happening (sorry, can't remember the exact details of the error...strong case for keeping a log of everything I work on and details).

I've included a snip of the events that occur just before the services quit working...

It seems like zimbramon is doing it's usual polling of services, it finds it can't communicate with the mta, so it tries to refresh the postfix configuration. No idea on this one. Posting configuration notes here...
