Hi,

We've got a couple of servers running FreeBSD 6.4-Stable - and
Sendmail 8.14.2.

We run three sendmails on these machines - the sendmail receiving mail
is set to DeliveryMode=Queue.

Another sendmail is run to do queue delivery runs (e.g. 'sendmail -
q30s'), there's a third that handles the submission queue (which is
rarely used).

The main dequeing sendmail process sometimes stalls though - this can
happen when the system is busy, or when it's quiet. 'ps' shows the
queue runner is in state 'pause'  (as it always is) - but there's no
processes running mail from the queue.

Looking at '/var/log/messages' shows plenty of mail coming in, but no
mail going out at all. If you HUP the process id, it restarts - and
springs back into life - and 'catches' up through the queue.

Anyone else seen anything like this?

Just wanted to check there's not a known issue/bug/problem/something
stupid etc. before I start looking at trying to attach gdb to it (and
dusting off my debug manuals ;)
