Maildir on NFS
This is the first time I've heard this happening with maildir. It's always been with mboxes before.
IMAP process crashes for certain (many, but not all) users when accessing certain folders (in the example below, in crashes when accessing my INBOX, about 1700 mails). I could access other mailboxes without problems. And a simple telnet to the imap port followed by a login works fine.
Any idea what the users were doing when it crashed? Was it just opening the mailbox or opening some mail or deleting/copying mails?
Erased the coredumps (was filling up the system too quickly) so I can't really produce a backtrace right now (had to back down to 1.0.13 again even though that one has another core-dump-generating problem - but that is atleast limited to only one specific user so far). Going to set up a separate test server to test things more without disturbing our normal operations...
Some kind of a way to reproduce this would be helpful. Or I guess in your case even a backtrace, since all the previous ones have been with COPY command and mbox.
mmap_disable: yes mail_nfs_index: yes
BTW. these can be "no" if you're storing indexes locally.
