Q: Some times my pages don't load or I can't see my mail box contents, it
seems to happen to random users at random times, after investigating a
bit I get the following log messages appearing from my IMAP server?:

date time linux inetd[458]: imap/tcp server failing (looping), service
terminated

Why is this?

A: This is a problem with inetd thinking that your imap server has a
problem or is under attack by a denial of service attack. The solution
is to tack a 'max connection' section onto the imap/inet definition:

imap stream tcp nowait.XXX root /usr/sbin/imapd imapd

It's in the man page for inetd, but the ".XXX" says that inetd should
allow a max of XXX connections per minute to imap before it sees it
as 'looping'. You should set XXX to a value that handles your load
but does not go far beyond it, this is usually determined
experimentally.
