I've been noticing idle pop3d processes on our Cyrus front end server for some time. These should be transient. One that was several days old had an established TCP connection to a wireless client that had disappeared. Presumably the client never closed the connection. Setting TCP keepalive on the file descriptor should permit the kernel to close the connection in this situation. Does this sound reasonable? Perhaps it's already been addressed in a later Cyrus version. We're running cyrus-imapd-2.3.8. I'm willing to add a `keepalive' option to Cyrus master along with the setsockopt() system call to enable that setting. This option could be added to the cyrus.conf file for any services that could benefit from it. Would this be a reasonable addition to Cyrus? -- -Gary Mills- -Unix Group- -Computer and Network Services- ---- 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
