If this is your own server, I'd recommend switching to Postfix and
using Maildir for message storage.  The problem with mbox format
message stores is that only 1 process can be writing to the file,
which stores *all* messages for a folder.  If you are receiving a new
message while deleting an existing one, all kinds of nasty things can
happen.

If you need POP3 (I'd recommend going with IMAP instead) then look at
Courier, Dovecot, or Cyrus.  They provide nice, fast, stable,
Maildir-support with POP3 and IMAP daemons that access the same
folders.
