we're running Cyrus 2.2.12 on RHEL3U7. about once a day (typically peak hours), we have a problem with lmtpd just "hanging": Jul 6 13:36:27 mail-imap3 lmtpunix[1578]: executed Jul 6 13:55:08 mail-imap3 lmtpunix[1578]: accepted connection Jul 6 13:55:08 mail-imap3 lmtpunix[1578]: lmtp connection preauth'd as postman note the 18 minute delay. during this time, there are no deliveries to this Cyrus. at this time, there's about 70% idle CPU and 6 GiB free RAM, so it shouldn't be resource constrained. IMAP service seems snappy as ever. this is the entry from cyrus.conf: lmtpunix cmd="lmtpd" listen="/uio/PKG/config/var/imap/socket/lmtp" prefork=2 we are running several instances of Cyrus on each cluster node, and this happens simultaneously to all instances on a given node. looking at the code, it seems the wait happens inside service/master.c:main, and probably is related to the lock file. is it possible there is a race condition? any ideas are welcome! -- Kjetil T. ---- Cyrus Home Page: http://asg.web.cmu.edu/cyrus Cyrus Wiki/FAQ: http://cyruswiki.andrew.cmu.edu List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
