Hi Fungai,

1. As discussed with Joe, I think you need to check your network and
possibly change the network adapter facing your local network to see
if that's the cause or not. The public adapter doesn't have any
issues, so it seems to me the problem is most likely linked to
hardware.

2. I did advise Joe some time back to add the following in dovecot.conf:

auth_worker_max_count = 300
auth_worker_max_request_count = 300

but I'm not sure if he did. This issue only seemed to appear in
dovecot with Ubuntu 9.04 (AFAIK and I'm not sure why). I do know at
least one other person who had the same issue with 9.04 Server and
adding those lines fixed the problem for them. Those are the only
fixes documented for that issue on the dovecot site, so you might want
to double-check that those lines appear in the conf. It's related to
the frequency of user pop3 logins and using standard system account
authentication. An alternative could be to change the authentication
method that dovecot uses, but since those conf changes fixed the
problem for someone else, that's the first place to check. You could
also try increasing the number for both.

Regards,
Neil
