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!
