Hi Timo, hi all! Today i noticed imap throws segmentation faults and dumps cores. I looked into logs I can see: 2013-03-07T12:12:52.257986+01:00 meteor dovecot: imap(marcinxxx@kolekcja.mejor.pl) <7sRXtFPXYAA+eX93>: Error: Corrupted dbox file /dane/domeny/mejor.pl/mail/marcin//.mdbox/mailinglists/storage/m.75 (around offset=2779212): EOF reading msg header (got 0/30 bytes) 2013-03-07T12:12:52.258052+01:00 meteor dovecot: imap(marcinxxx@kolekcja.mejor.pl) <7sRXtFPXYAA+eX93>: Disconnected: Internal error occurred.

doveadm -v force-resync -u marcinxxx@kolekcja.mejor.pl "mailinglists.*" doveadm(marcinxxx@kolekcja.mejor.pl): Warning: fscking index file /dane/domeny/mejor.pl/mail/marcin//.mdbox/mailinglists/storage/dovecot.map.index doveadm(marcinxxx@kolekcja.mejor.pl): Warning: mdbox /dane/domeny/mejor.pl/mail/marcin//.mdbox/mailinglists/storage: rebuilding indexes Segmentation fault
How should I repair mdbox file?
I have another question, doveadm force-resync -A "*" doesn't do resync
inside namespace. Is it feature or bug?;)
Thanks, Marcin
