Based on feedback that I received from CMU & a few list members, we re-compiled cyrus-2.0.16 to use a flat file for the mailboxes.db last night. We then re-enabled IMP 2.x this morning. It has been running for about 5 hours now without the run away imapd's that we noticed on Monday. Hopefully we are "back to normal".
Many thanks to those that responded - it definitely helped us track down the problem (I hope). -chris Chris Peck Manager of Unix Services Information Technology The College of William and Mary Williamsburg, VA 23187
