fatal: Queue report unavailable - mail system is down

[nate.wheeler]

I've got a problem that has happened twice now. I come into work and the server doesn't send or receive mail, but I can log into the web interface.

/var/log/zimbra.log has this in it:

Apr 22 06:26:00 mail postfix/postqueue[11570]: fatal: Queue report unavailable - mail system is down

A "zmcontrol status" shows everything running. So to get it back up I just stop and start it, then everything is fine.

I googled a bit and took a look at my catalina.out in tomcat. There are some errors that have got to do with it. The log is attached.

Also every night I stop zimbra, backup, and then start it again.

[nate.wheeler]

no ideas on this one?

Is your sshd running OK on the server ?

[nate.wheeler]

yeah, just fine

[uxbod]

How much memory does your ZCS server have ? Anything else running on it ? Could you post a top and a free please.

[nate.wheeler]

It has 3 gigs of RAM. Just Zimbra runs on this except for a couple backups each night which takes a bunch of RAM because it compresses. The graph is the RAM usage for a week. You can see each night when it runs the backups.

The same happened here yesterday.

The server stopped for backup at 7pm and started again.

Zimbra said everything is running. But the same error occured:

I've got the same problem. I come into work and the server doesn't send or receive mail, but I can log into the web interface.

/var/log/zimbra.log has this in it:
