What's going on with your OS?  It looks like something isn't locking 
properly!

Can you look for other lines mentioning that mailbox in your syslog?

Can you show me your ./configure line, and any patches you are applying 
to 2.4.10 (if you are)

If it's the same user, can you please make a directory 
$confdir/log/muehlfeld - writable by user cyrus - so you can show the 
commands that the user is running when this happens.

Thanks,

Bron.
