A NOTE has been added to this issue. ====================================================================== http://www.dbmail.org/mantis/view.php?id=1024 ====================================================================== Reported By: rmoesbergen Assigned To: ====================================================================== Project: DBMail Issue ID: 1024 Category: IMAP daemon Reproducibility: always Severity: major Priority: normal Status: new target: ====================================================================== Date Submitted: 09-Sep-13 10:15 CEST Last Modified: 09-Sep-13 17:07 CEST ====================================================================== Summary: Imap daemon leaks extensive amounts of memory Description: During load tests we discovered that the dbmail-imap daemon leaks memory eventually causing the machine(s) that it runs on to OOM and start killing processes. Memory usage seems dependant on the amount of messages in the database, but only ever increases when more messages are sent and received, even though the messages are deleted after retrieval.
This bug is probably masked in a default installation due to the fact that the default logrotate script restarts all dbmail daemons every day, resetting memory usage. We've modified this script because this restart would cause unwanted downtime (we have very strict SLA's with our customers) ====================================================================== ---------------------------------------------------------------------- (0003576) paul (administrator) - 09-Sep-13 17:07 http://www.dbmail.org/mantis/view.php?id=1024#c3576 ---------------------------------------------------------------------- I've passed along the valgrind results to the libzdb author, and he urges you to upgrade libzdb: """ Please use the last version of libzdb (2.12). I see you use libzdb.so.8.0.3 in the log you sent and there has indeed been memory problems related to MySQL, but those should have been fixed back in 2.11.2 """ Issue History Date Modified Username Field Change ====================================================================== 09-Sep-13 10:15 rmoesbergen New Issue 09-Sep-13 10:15 rmoesbergen File Added: vg.log 09-Sep-13 17:07 paul Note Added: 0003576 ====================================================================== _______________________________________________ Dbmail-dev mailing list Dbmail-dev@dbmail.org http://mailman.fastxs.nl/cgi-bin/mailman/listinfo/dbmail-dev
