I have seen issues with pop3d's locking up some weeks agao while 
maintaining our University's Cyrus IMAPD installation.

It turned out to be caused by the used file system for /var/lib/imap. We 
used reiserfs there - the system itself is a openSUSE 11.1 and has been 
older SUSE-variants before.

After reformatting with xfs, which we have used for the mailbox 
partitions everything went smooth again.

I didi not follow this issue, as the system had to be running without 
flaws in the shortest possible time.

This should be no reiserfs-bashing. I use it frequently without 
problems, but here it broke something.
