MTA Going Down After Full Backup

[jpsinacola]

I am trying to troubleshoot a problem with my installation, specifically the MTA service going down on Saturday morning, during which I presume my full backup. It does it every Friday night / Saturday morning and I need to start services and it comes backup up without any problems. I have looked through the logs and I found that the full backup completes. I guess my first question is, does the MTA shut down during full backup? In the log, after it gives the backup detail, says ExceptionID:btpool10-54701:myserver/soap/sendmsgrequest: messageID
Code:mail.TRY_AGAIN.

I can post more of log if needed, but was wondering if anyone else had experienced that problem?

Thanks!

I guess my first question is, does the MTA shut down during full backup?

No, the MTA doesn't shutdown after any sort of backup.

In the log, after it gives the backup detail, says ExceptionID:btpool10-54701:myserver/soap/sendmsgrequest: messageID
Code:mail.TRY_AGAIN.

I can post more of log if needed, but was wondering if anyone else had experienced that problem?

You need to post more details from the log files after the moment the backup finishes to to the time after the MTA shuts down (I assume you're seeing a shutdown in the log files?).

Thanks for that info Bill, that helps a lot. So something is knocking that service offline then. I am not seeing a specific instance where it shuts down, I just see that mail.TRY_AGAIN. I am looking for more information from the MTA service itself. Here is more from the log:

IS the service actually down at this point, what's the status of the services after the backup is done? Post the output of the following command:

zmcontrol status

Does this happen with all users? Has this problem just started? Any upgrades to the server recently? If all the services are still up and running are the accounts in maintenance mode?

[jpsinacola]

At that point, yes, the MTA service is down. All other services are running. I cannot provide the output now because all of the services are currently up. Every Saturday morning I have to VPN in to my network, I check it with zmcontrol status, I see that MTA is not running (everything else is), and I do a zmcontrol start and it starts running again and all appears normal.

This has been going on for about a couple of months, I do not have the date exactly, sorry. I have not done any software updates, neither Zimbra nor SUSE during that time frame.

I wish I had more to go on, which is why I turned to the forums hoping maybe someone had something similar, or let me know where to even start looking.

**
Upon more thought, I understand your question. Am I SURE that the backup is causing it? No, not exactly. There is nothing in the logs to show where is went down, so you could call it a "deduction" since the full backup is the only thing that is different. Other than this issue, I have ZERO problems with Zimbra and it runs wonderfully. So, I need to figure out how best to monitor it, so that I know exactly WHEN it goes down. Thoughts?

Thanks again for the help!

Do you have any monitoring software (such as Nagios) on your LAN or something just to check port 25 to see when exactly the MTA is stopping? Is this a VM or a bare metal server?
