LmtpServer Error

[Jone dos Santos]

hi guys I'm not sure if this is part of the forum I should post but I think that's what's closest to my problem.

in a constancy of two weeks the zimbra server comes with the following error on mailbox.log:

22/02/2011 12:01:37,426 INFO [LmtpServer-3582] [ip = xyzw;] ProtocolHandler - I / O error
while processing connection: java.net.SocketException: Socket closed


important when this error occurs the user can not login to web interface and sending and receiving emails is paralyzed

How can I fix?

Thanks

can you show the output of "nmap 127.0.0.1" when you see that log?
With that command, you can know with port is openned.

By default, zimbra accepts 5 simultaneous IMAP connections per user. You should try to increase that:
root@mail:~# su zimbra
zimbra@mail:/root$ /opt/zimbra/bin/zmlocalconfig -e zimbra_session_limit_imap=50
zimbra@mail:/root$ /opt/zimbra/bin/zmcontrol restart

[phoenix]

root@mail:~# su zimbra

That command should always be:

su - zimbra

The hyphen is important to create the correct environment.
