Unfortunately it's too late... To see what is causing the problem,
you need to look at it while the problem is happening...
There might be something interesting in syslog, but I'm sorry to say,
there probably won't be. If you want to post them on a website, maybe

The syslog is filled with (30MBs of it):
Jun 28 09:20:33 mx1 dbmail/pop3d[6383]: pool.c,manage_stop_children:
General stop requested. Killing children..
And after that:
