A NOTE has been added to this issue. ====================================================================== http://www.dbmail.org/mantis/view.php?id=1057 ====================================================================== Reported By: casper Assigned To: ====================================================================== Project: DBMail Issue ID: 1057 Category: POP3 daemon Reproducibility: always Severity: major Priority: normal Status: new target: ====================================================================== Date Submitted: 19-Sep-14 10:09 CEST Last Modified: 19-Sep-14 14:26 CEST ====================================================================== Summary: pop3 daemon leaks sockets' filedescriptors Description: lsof -p 12345 reports:
dbmail-po 30236 dbmail 43u sock 0,7 0t0 14855254 can't identify protocol dbmail-po 30236 dbmail 44u sock 0,7 0t0 14855656 can't identify protocol dbmail-po 30236 dbmail 45u sock 0,7 0t0 14855262 can't identify protocol dbmail-po 30236 dbmail 46u sock 0,7 0t0 14861487 can't identify protocol The number of sockets keeps rising, until the ulimit for filedescriptors is hit and accept() cannot create a new socket because of it. I've worked around by setting a very high limit and do a scheduled pop3 daemon restart. ====================================================================== ---------------------------------------------------------------------- (0003679) casper (reporter) - 19-Sep-14 14:26 http://www.dbmail.org/mantis/view.php?id=1057#c3679 ---------------------------------------------------------------------- The issue seems to be caused by the keepalived loadbalancer that is placed in front of my pop3 servers. I have keepalived configured to do a TCP check. It opens a connection to a port. As soon as the connection is accepted, it's terminated by keepalived.
