Hi, I have a cyrus imap server on a Centos 5 VM that's hosted. Its cyrus-imapd-2.3.7-7.el5_4.3 The hosting company were doing maintenance and rebooted my VM. Errors like this appeared in /var/log/maillog after startup. master[3147]: about to exec /usr/lib/cyrus-imapd/ctl_cyrusdb ctl_cyrusdb[3147]: recovering cyrus databases ctl_cyrusdb[3147]: skiplist: recovered /var/lib/imap/mailboxes.db (73 records, 12360 bytes) in 2 seconds ctl_cyrusdb[3147]: skiplist: recovered /var/lib/imap/annotations.db (0 records, 144 bytes) in 3 seconds ctl_cyrusdb[3147]: done recovering cyrus databases master[3148]: about to exec /usr/lib/cyrus-imapd/idled {snipped the imap & pop startup messages} ctl_cyrusdb[3150]: checkpointing cyrus databases lmtpunix[3155]: DBERROR db4: /var/lib/imap/deliver.db: unexpected file type or format ctl_cyrusdb[3150]: DBERROR: error listing log files: DB_NOTFOUND: No matching key/data pair found lmtpunix[3155]: DBERROR: opening /var/lib/imap/deliver.db: Invalid argument cyrusdb[3150]: DBERROR: archive /var/lib/imap/db: cyrusdb error lmtpunix[3155]: DBERROR: opening /var/lib/imap/deliver.db: cyrusdb error ctl_cyrusdb[3150]: DBERROR: error listing log files: DB_NOTFOUND: No matching key/data pair found ctl_cyrusdb[3150]: DBERROR: archive /var/lib/imap/db: cyrusdb error ctl_cyrusdb[3150]: archiving database file: /var/lib/imap/annotations.db ctl_cyrusdb[3150]: archiving database file: /var/lib/imap/mailboxes.db ctl_cyrusdb[3150]: DBERROR: error listing log files: DB_NOTFOUND: No matching key/data pair found ctl_cyrusdb[3150]: DBERROR: archive /var/lib/imap/db: cyrusdb error ctl_cyrusdb[3150]: done checkpointing cyrus databases lmtpunix[3155]: FATAL: lmtpd: unable to init duplicate delivery database master[3137]: process 3150 exited, status 1 {snip} lmtpunix[3235]: DBERROR db4: /var/lib/imap/deliver.db: unexpected file type or format lmtpunix[3235]: DBERROR: opening /var/lib/imap/deliver.db: Invalid argument lmtpunix[3235]: DBERROR: opening /var/lib/imap/deliver.db: cyrusdb error lmtpunix[3235]: FATAL: lmtpd: unable to init duplicate delivery database master[3137]: process 3235 exited, status 75 master[3137]: service lmtpunix pid 3235 in READY state: terminated abnormally master[3236]: about to exec /usr/lib/cyrus-imapd/lmtpd etc etc I have recovered cyrus from the backup directories, but this surely this shouldn't happen. I have another similar setup on a 64 bit Centos 5 machine where I've never seen this error. I've checked the SysV init scripts to see if cyrus is being shut down properly. It seems to be, its last log messages before reboot were... master[4053]: process 5187 exited, status 0 master[4053]: process 5278 exited, status 0 Any ideas Thanks Ken -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/
