Please give us more information.  For starters, your cyrus version number
(along with the rest of the output of the cyradm 'ver' command) would be
useful.

Also, what files are open by what processes.  Taking sample lsof outputs
of lmtpd and imapd processes would probably be helpful.

There have definately been file descriptor leaks in some versions of
cyrus, but all known ones have been resolved in more recent versions.
