Solved all of my lmtpd hanging problems.
I see you are using RPMs so I guess you would have to compile from source to make the change.

Hi,
while testing our server setup we've found a (to me) strange behavior of lmtpd. Here's the setup:
name : Cyrus IMAPD
version : v2.1.9-Invoca-RPM-2.1.9-10 2002/08/30 18:40:23
vendor : Project Cyrus
support-url: http://asg.web.cmu.edu/cyrus
os : Linux
os-version : 2.4.18-4SGI_XFS_1.1bigmem
environment: Cyrus SASL 2.1.5
Sleepycat Software: Berkeley DB 3.3.11: (July 12, 2001)
OpenSSL 0.9.6b [engine] 9 Jul 2001
CMU Sieve 2.2
TCP Wrappers
mmap = shared
lock = fcntl
nonblock = fcntl
auth = unix
idle = poll
dirhash = full
mboxlist.db = skiplist
subs.db = flat
seen.db = skiplist
duplicate.db = db3-nosync
tls.db = db3-nosync
[root@lvr1 raddb]# rpm -q cyrus-sasl
cyrus-sasl-2.1.7-2
(This is the RedHat 8.0 RPM that I installed under RedHat 7.3)
First off, I'm a bit surprised that 'version' only shows the version of SASL that IMAPD was compiled against, not the current version ... that's just cosmetic, I guess.
Anyway, we are also running sendmail 8.12.6 with the cyrusv2 mailer. All seems to be fine if we launch cyrus-imapd first and sendmail second. However, if we stop cyrus-imapd for whatever reason without stopping sendmail first, we end up in a situation where the lmtpd gets stuck upon a restart of cyrus-imapd. To be precise, it doesn't accept connections from sendmail and if we strace it all we see is:
accept(4,
That's it. The workaround then is to stop both sendmail and cyrus-imapd and to wait for several minutes. After that, if we start the processes in the right order, everything is fine again.
Is this behavior to be expected or is it a bug?
Thanks, Sebastian Hagedorn
