Gotta love responding to mails from 2 1/2 years ago, but I haven't seen a
solution here yet.
Anyway, I ran across this same problem on our system with 50K+ users, so we
really needed to have "quota -f" working. After being thrown off by this
analysis for a while (it closes the 4th file descriptor a bit later in the
truss output), truss actually provided me with the clues. It was trying to
open /var/spool/cyrus/default/user/INBOX/cyrus.header, which didn't exist (not
surprisingly, since it's a stupid name for a user).
It turned out that this came from the file mailboxes, which is in the
configdirectory as defined in /etc/imapd.conf. I'm going to go out on a very
small limb and say that this mailbox was created when the sysadmins were
trying to work out what was going on and didn't clean up after themselves.
So, run
truss -t open quota -f
and look for the file that it fails to open and work out why it's there.
Hope this is still useful to someone.
