There's a known problem with Sendmail V8.9.1 and DB2.1.14.
Please take a look at DejaNews, there is an option for DB2
which you need to enable as a workaround.
Or simply use the Sun map type (dbm) till the next release
(8.9.2 will fix this problem).

comp.mail.sendmail
It's
--enable-diagnostic

The other known fix is to recompile db-2.4.14 with the --enable-diagnostic
flag, then recompile your sendmail with that new db.

Original Question:
I recently upgraded our sendmail to v8.9.1 on our SunOS 4.1.3U1
mail hub. It works really good for stopping relaying through
our site. My problem is that I now have processes that tend
to hang for incredibly long periods of time. It is as if the
sendmail processes never time out/complete.
I have read every faq on sendmail I can find, my partner in
crime has went through the sun-managers archives to no avail.
I did install the required patch to the SunOS. Patch 102010-06
which I felt was going to address the problem.
(security denial getsockopt RESET trap leak bus TCP SYN)
The processes continue to hang until the load climbs to 12
and then my sendmail stops accepting input.
I have tweaked on all of the sendmail.cf timeout values
trying to speed up things to get things to time out quicker
but none of that has been any help.
the following are the timeout values as I have them set now.
(I have tried many combinations of things to no avail)
I also turned ident off:
OrIdent=0
# open connection cache timeout
#O ConnectionCacheTimeout=5m
O ConnectionCacheTimeout=1m
#O Timeout.initial=5m
O Timeout.initial=1m
#O Timeout.connect=5m
O Timeout.connect=2m
#O Timeout.iconnect=5m
O Timeout.iconnect=1m
#O Timeout.helo=5m
O Timeout.helo=1m
#O Timeout.mail=10m
O Timeout.mail=1m
#O Timeout.rcpt=1h
O Timeout.rcpt=10m
#O Timeout.datainit=5m
O Timeout.datainit=1m
#O Timeout.datablock=1h
O Timeout.datablock=10m
#O Timeout.datafinal=10m
O Timeout.datafinal=1m
#O Timeout.rset=5m
O Timeout.rset=1m
#O Timeout.quit=2mO Timeout.quit=30s
#O Timeout.misc=2m
O Timeout.misc=30s
#O Timeout.command=1h
O Timeout.command=10m
#O Timeout.fileopen=60s
O Timeout.fileopen=60s
#O Timeout.ident=30s
#O Timeout.hoststatus=30m
O Timeout.hoststatus=1m
Thanks in advance for any light anyone can shed on this
problem.
