All of them appear locking-related, or just the assertion failure?
My best guess is that all problems are result of locking problem.
Same configuration here. We use flock with UW IMAPd (no dotlocks) and procmail, and it seems to work fine.
Maybe there is some issues with flock on GFS, have you tried dotlocking with Dovecot?
Glad to meet someone using Polyserve. Can you tell me more about your cluster? Is it just for mail access? How many nodes? How many users?
For now it's just a small lab setup with two RHEL 3 nodes, no real 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?
No, it's just for a performance.
