Yes, over the last 7 days it didn't happen on one day, Thanksgiving. I would probably attribute that to very low load. On a regular basis ? Yes. I generally notice it between 6-9AM. At backup time ? We are not running backups on this host. Disk nearly full ? We have plenty of space left on all partitions. Some DBERROR in the logs somewhere ? There were, but not anymore. In troubleshooting the issues we converted deliver.db to skiplist rather then BDB which eliminated the errors. They looked like this. Nov 26 19:24:49 imap06 lmtpunix[28264]: DBERROR db4: 15 lockers service imapd restart is enough ? Nope, the box has to be cold booted. Hitting the physical reset button. ---- 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
