Good Day

I am having the following serious problem. I am running CentOS 4.1 with dovecot 0.99.11. The users are using POP3 login to retrieve mail. For the last 2 days we have experienced the following problems. I have recreated all the users and reconfigured the dovecot,but the same problems occur.

Please see attached /var/log/maillog messages It appears so users login whereas others cant.Eventually after about an hour none of the users can login.

If I tried to restart the dovecot i get the following error

Fatal: Listen (110) failed: Address already in use

Is this because it is trying to restart when all the processes havent been killed?

Your help would be much appreciated

Kind regards
