Exactly. It's the 40-connections-per-minute limit in inetd.
Use the change I posted in my last mail and your problems should
be gone. If you are getting more than 5000 pop-3 connections per
minute, you can go for even more, but you'll probably have worse
problems than inetd limits in that case... :-)
BTW: this is mentioned in the inetd man page; it's not the easiest
man page to read, but for a network administrator I'd strongly
recommend reading it carefully through some time when you aren't
horribly busy so that it all sticks in your mind the next time a
disaster hits... :-)
