[Dovecot] Tracing a server problem

I have a Linux CentOS server, 4 Gb RAM, with 50 IMAP users.
The server is connected to LAN via a firewall appliance, no filtering applied.

Many users with different clients complain a lot of "server disconnected" errors.

On the server side Doveco does not report any kind of error. I just ab an
unusual rate of "IMAP(xxxxxx at xxxx): Disconnected: Logged out" entries.

Given that I am NOT sure about the ethernet an firewall performance, how can I
trace this problem?


Dovecot is 1.1.10, configured with --with-mysql --with-ssl=openssl
- --disable-ipv6 --sysconfdir=/etc --localstatedir=/var

Userbase is mysql only.




Ciao,
