Suddenly loads of errors in my daily report

[BarefootPanda]

Hey guys, last night I started to get the "zmmailboxdctl is not running" deal and it's gone down twice. I looked through my logs (blindly) and didn't find anything, but this morning I was looking through the daily log and have a large list of errors.

When mailboxd goes does I get...

Jul 18 07:06:19 Zimbra-Mail zimbramon[29210]: 29210:err: Service status change: mail.northbrain.com mailboxd changed from running to stopped\n

I also wonder why there are so many senders and recipients. Is there a wiki for the report that would help make it clearer?

I'm going to post my long list of errors to see what you guys think. Thanks. Hopefully we can get zmmailboxdctl to stay running!

Also, I'm leaving the IP and domain name there just because I don't have time this morning to fix up this post. If this is a huge no no then I'll remove it later.

Most probably backscatter. Perform a search on the forums for it
