A user just tried to use OSX 10.3's Mail.app via imap. It caused the process to start eating CPU, and this in the logs. Any idea what could be happening here? What information should I get on his setup?

imap(fenner): Nov 03 14:30:37 Error: Timeout while waiting for release of exclusive fcntl() lock for index file /home/f/fenner/M>aildir/.INBOX/.imap.index
