Dovecot is running on RHEL 3, on top of Redhat/Sistina GFS (clustered filesystem.) Currently I'm keeping it on one node to avoid possible GFS locking issues. I'm running with mmap_disabled=yes, mbox format. Most of the 1.0-test builds I have done eventually corrupt their index files, and show strange behavior (click on a message in the folder view, and an entirely different message opens... delete three or four messages and expunge, the messages instantly reappear as unseen.). I typically wipe the .imap directories between different builds of Dovecot. I've been following the -test code for a couple of months now, just to see how it does, because we're running UW IMAPd and are excited to have a way to increase the performance of our mail cluster (indexes) without having to move away from mbox. Let me know if there's more information I could provide that would be helpful. Jim [View Less]

[Dovecot] Excessive imap_login processes
by Keith Edmunds 02 Dec '04

02 Dec '04

I'm running Dovecot on a very small mail server (never more than six users accessing IMAP, often fewer). I'm seeing the number of imap_login processes grow over time, and right now there are 23. All the "login_process_*" settings in dovecot.conf are commented (ie, at their defaults). Is this a known or expected issue? The version of Dovecot is 0.99.10.8, which I accept is perhaps a little old. Thanks, Keith
