The normal -bd -q30m

Still running 8.7.5/8.6.9

At the moment, there are 21 sendmail processes, but only 11 SMTP connections
(netstat -f inet | grep smtp |wc -l).  Most connections are in CLOSE_WAIT
state, three in TIME_WAIT and one in SYN_SENT.

Nothing that I can see.  Lots of messages about successful deliveries and
normal problems (there was one machine which didn't accept mail for some
time, so I have timeout messages in /var/log/maillog).  No errors in
/var/log/messages.

All but one (the original sendmail process) are sleeping on 'lockf'.

The memory hogging processes are trying to deliver queued mail.  It
seems every sendmail process that is launched gets in this state now.
The first one was started when I rebooted the machine and the others
at 30 minute intervals.  No sendmail process has exitted.  Some are
trying to deliver the same message, most are "working" on different
messages.
