    Default zimbra does not accept connection

    Hello all,

    Today (and also yesterday) my zimbra server doesn't respond when users try to login, send mail etc.

    I see this in mailbox.log

    Code:
    2008-05-14 08:25:01,545 WARN  [Pop3Server-18] [name=user@domain.com;] dbconn - Connection pool is 75% utilized (9 connections out of a maximum of 10 in use).  Turn on debug logging for zimbra.dbconn to see stack traces of connections not returned to the pool.

Turn on debug logging for zimbra.dbconn to see stack traces of connections not returned to the pool.
    I had to reboot server.

    How can I solve this?
    Thanks for help.

    How many users are connecting ? You could have a read of this wiki entry on connection pools :- Performance Tuning Guidelines for Large Deployments - Zimbra :: Wiki
