IMAP failing daily

[tmallardi]

Hello,

In the last week or so, I've discovered that IMAP fails early some mornings. Restarting IMAP from cPanel does work. So I have to reboot the server.

Where should I begin to troubleshoot this issue. (I'm a beginner.)

Thanks in advance.
Tim

Hello,

You can review /var/log/maillog at the time of the failure to see if you notice any particular error messages.

Thank you.

Thanks Michael.
This issue appears to be a problem that others have reported with dovecot.
From what I read, the issue will be resolved with the next release of WHM.

Would you mind sharing the specific thread or case number you are referring to?

For reference, here's the fix from the other post quoted from cPanelPeter:

Hello,

We had a case on this (Case # 187313) which has been fixed as of 11.48.5. In the meantime you need to kill any hung Dovecot processes.

Something like the following should do it:

# for i in `ps aux | grep dovecot | awk '{print $2}'` ; do kill -9 $i ; done

Then you should be able to restart Dovecot with:

# /usr/local/cpanel/scripts/restartsrv_dovecot
