  I am aware of that particular issue, but this does not appear to be it.
/tmp has plenty of space, and it has not been full for any of our checks.

  There are some large mailboxes, in the 100+ MB range, with thousands of
messages in them.  As we know, UW-IMAP likes to do full-rewrites of the
mailbox data.  It also has to read through and index the folder on every
open.  Combine this with MS Outlook, which appears to close and re-open the
IMAP session more often than the UW people expect.  Additionally, they run
the MS-Windows equivalent of an IMAP "xbiff" on each PC, which appears to
cause file lock contention/breaking issues.

  Moving to Cyrus IMAP (or other, similar systems) sounds good for a number
of reasons.  Deletes/expunges are much more efficient.  Indexes are kept on
disk.  One-file-per-message drastically reduces the chances of lock
contention.

  At least, that is the theory.  It remains to be seen how well it will work
in practice.  :-)
