[PERDITION-USERS] Perdition stops listening on imap port

Hi guys, Suddenly seem to be having a problem with perdition.imap4. It stops listening on the imap port. netstat -l shows all other Perdition services listening (imaps,pop3,pop3s) fine but not imap. We also still have imap4 processes running: nobody 17589 0.0 0.4 5388 2220 ? S 16:18 0:00 perdition.imap4: auth ok nobody 17595 0.0 0.4 5520 2384 ? S 16:18 0:00 perdition.imap4: auth ok etc Nothing seems to be logging. Connecting to the server on 143 shows as expected: [root@tg1 perdition]# telnet localhost 143 Trying 127.0.0.1... telnet: connect to address 127.0.0.1: Connection refused telnet: Unable to connect to remote host: Connection refused A restart has it working fine for 10 minutes to a few hours then it drops again. Perdition version is 1.17 Any ideas what else I can do to find out why it is dropping the port? -- Squirrelmail Stable 1.4.8 PHP 5.x Hardened with Eaccelerator Apache 2.x Imapproxy over Dovecot/Maildir all running on Gentoo Linux for ~5,000 users.
