There could be many reasons. Look in syslog for clues.There can be many reason, ranging from the simplest to solve -- courier-imap has settings on the maximum number of connections accepted from the same IP address, before dropping any more connections; to the hardest -- you're running out of some other resource, such as the maximum number of processes or file descriptors. The first place to look would be syslog.
