Did check the auto backup files before too, but they were all identical. It was too late probably. Then I used the skiplist.py from here: http://oss.netfarm.it/python-cyrus.php python ~/skiplist.py mailboxes.db >mailboxes.txt rn mailboxes.db mailboxes.err cvt_cyrusdb /var/lib/cyrus/mailboxes.txt flat /var/lib/cyrus/mailboxes.db skiplist chown cyrus mailboxes.db Fixed! Okay then, now it works, but how often will an error like this occur, can I do something to prevent it? First I thought of "0090" as some sort of error code, and I found only two error incidents with /line/ 0090 in Google... ;) ...but it is much more numerous. Can this be related to shutting down and rebooting the system? Could be a coincidence of course, but just after rebooting the error was there. Can it be related to Squatter? By default, Squatter was not set, but some days before the error I set Squatter to an hourly "nice" run. Now I turned it off again. > You should also setup a cronjob to dump the mailboxes.db file to plaintext > periodically (so it can be backed up).

This has to be written to /etc/crontab like Squatter, correct? How often should it be running? Maybe it's only neccessary when new IMAP users and/or folders have been created?? Thank you for all help! I feel queasy with an error that has no apparent reason. I wanted to build a system that can run without administration for months and, maybe, would sustain even a rare power failure. But there was no power failure and no sign of a disc error either... :-( Kind regards, Gregor ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
