Same configuration here.  We use flock with UW IMAPd (no dotlocks) and 
procmail, and it seems to work fine.  We could use fcntl, but it has 
more overhead.

cluster?  Is it just for mail access?  How many nodes? How many users?

All the mail is stored on RAID-10, mailboxes and indexes.  Splitting up 
the spindles might help somewhat, but having them together shouldn't 
cause problems like this, right?
