I have a server problem.
Login e-mail is a problem. IMAP connection is lost, and the e-mail program says connection to server can not connect.
I tried to log on to webmail. RoundCube loading for a long time (end of login to roundcube). SquirrelMail says: Connection dropped by IMAP

After a while the server will send an email to: FAILED: imap is my.server.net
Reason: Timeout while trying to get data from service: Died at /usr/local/cpanel/Cpanel/TailWatch/ChkServd.pm line 812.

And in a few minutes, I get new server mail: RECOVERED: imap on my.server.net
Reason: TCP Transaction Log:
<< * OK [CAPABILITY IMAP4rev1 UIDPLUS CHILDREN NAMESPACE THREAD=ORDEREDSUBJECT THREAD=REFERENCES SORT QUOTA IDLE ACL ACL2=UNION STARTTLS] Courier-IMAP ready. Copyright 1998-2011 Double Precision, Inc. See COPYING for distribution information.
>> A001 LOGIN __cpanel__service__auth__imap__3aec…..
<< A001 OK LOGIN Ok.
>> A002 LOGOUT

Now, IMAP works again! Yippee! Thanks cPanel Service Monitor :)
But would any ideas why this happens? I think it was the third time this month.

Hello :)

I recommend checking the /var/log/maillog file for the date/time that IMAP failed and see if you notice any particular entries that would help explain why it failed. It's possible the maximum number of authentication daemons was reached, or IMAP was running but failed to respond quick enough to yield a positive result to Chksrvd.

Thank you.
