No. In fact they are not errors but informational messages, so in newer versions of cyrus imapd you will see Jul 8 15:39:28 atlanta lmtpunix[29159]: [ID 366844 local6.info] DBMSG: 2279 lockers Jul 8 15:51:34 atlanta lmtpunix[29077]: [ID 366844 local6.info] DBMSG: 2249 lockers Jul 8 18:12:14 atlanta lmtpunix[4289]: [ID 366844 local6.info] DBMSG: 1583 lockers lmtpunix wants to open delivery.db which normally is a DB4 backed database unless you have changed the default in imapd.conf. Some old DB4 version had the problem of not releasing these locks so there was an overflow after some time. If the number of lockers keep growing without every becoming smaller from time to time you are running in this bug. -- Pascal Gienger University of Konstanz, IT Services Department ("Rechenzentrum") Electronic Communications and Web Services Building V, Room V404, Phone +49 7531 88 5048, Fax +49 7531 88 3739 ---- 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
