[Mimedefang] MD Lock-Ups occasionally

Lately on just one machine, I am seeing MD just end up in a hung state.
Restarting MD seems to get everything back on track. Running MD 2.63 and SA
3.1.4 on this box. This started a few weeks ago with MD 2.57 and I've been
tweaking things since. About the same time this started happening though, I
did start seeing the definition files for uvscan take a large jump in size.
Anyway, this is a three part question:
1 - What's the best command to run to see what might be occurring when it is
locked up?
2 - What's the best command to run to simply check that MD is alive and if
not restart the multiplexor and children?
3 - On this same machine, I'm seeing some VERY long sendmail processes stuck
in user open. These could be the cause for the hang or they could be
unrelated:
For example:
root 30588 0.0 0.1 7960 4760 ? S Oct16 0:15 sendmail:
./l9DGFVLL020125 postoffice.telstra.net.: user open
root 13000 0.0 0.1 7912 4708 ? S Oct16 0:15 sendmail:
./l9DDo4vt032194 mail.blonnet.com.: user open
root 27763 0.0 0.1 7800 4628 ? S Oct16 0:14 sendmail:
./l9BJpgoO011662 mx.lyricsfreak.com.: user open
root 8276 0.0 0.1 7816 4592 ? S Oct16 0:14 sendmail:
./l9DAYfog032104 mail.ppmusic.com.: user open
root 19580 0.0 0.1 7892 4588 ? S Oct16 0:12 sendmail:
./l9GKUvEd015228 mx.atomis.com.: user open
I am using these timeouts (Ken Cormack's I believe):
dnl TIMEOUTS (MANY OF THESE)...
define(`confTO_IDENT', `0s')dnl
define(`confTO_INITIAL', `30s')
define(`confTO_CONNECT', `30s')
define(`confTO_ICONNECT', `30s')
define(`confTO_HELO', `1m')
define(`confTO_MAIL', `2m')
define(`confTO_RCPT', `2m')
define(`confTO_DATAINIT', `2m')
define(`confTO_DATABLOCK', `2m')
define(`confTO_DATAFINAL', `5m')
define(`confTO_RESET', `1m')
define(`confTO_QUIT', `1m')
define(`confTO_MISC', `2m')
define(`confTO_COMMAND', `1m')
define(`confTO_IDENT', `0s')
define(`confTO_FILEOPEN', `1m')
define(`confTO_CONTROL', `1m')
define(`confTO_HOSTSTATUS', `5m')
Am I missing a timeout that could perhaps limit an entire email to take no
more than say 30 minutes?
Thanks for reading.

KAM
