We just upgraded to 2.2.13-10+etch2 and now our 64bit front end machines cannot connect to our back end servers, e.g., Sep 13 11:55:49 mfe5 cyrus/mc2pop3[6764]: connect(mbe2.msomt.modwest.com) failed: Invalid argument Sep 13 11:55:49 mfe5 cyrus/mc2pop3[6764]: couldn't authenticate to backend server also: Sep 13 15:15:39 mfe5 cyrus/mupdate[1327]: Thread timed out waiting for listener_lock A 32-bit front end machine is working fine. We don't think there are any other differences between these installations. cyrus.conf, mupdate.conf, and imap.conf are identical except for the obvious, listen addresses, hostnames. Any ideas or experience with this? -- John Masterson http://modwest.com ---- 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
