I seem to be having a very peculiar problem with cyrus 2.1.15. We recently had a system crash over the holidays (while no one was monitoring the server) wherein the root filesystem went read-only and (somehow) the cyrus log files grew to fill the partition (with mail.err and mail.log being over 10GB each).
After removing and resetting the log files and rebooting the machine, everything seemed fine save for one thing: some mailboxes seem to no longer be able to set flags on messages. For example, for most users, messages don't stay marked as read, but get marked as "not read" every time the mailbox is re-read. Oddly, this doesn't happen to all mailboxes; for some accounts this information is retained. I thought this might have something to do with permissions on, say, the cyrus.index file in the mailbox directory, but I compared permissions between a "good" mailbox and a "bad" one, and the permissions on all cyrus.* files were identical. Does anyone have any ideas about this? Also, this is probably in some documentation somewhere, but how does one reduce the amount of information being logged by cyrus? I looked in the /etc/cyrus.conf file, but couldn't find anything relevant.
