I am also running Sendmail v8.12.6 with MIMEDefang v2.21, with even more
aggressive settings:
MAX_SLAVES=20
MIN_SLAVES=10
BUSY_TIMEOUT=300
IDLE_TIMEOUT=3000
I have not experienced any issues similar to yours on any of the
machines I have setup like this, so I don't think the problem is
anything inherent in those two softwares, or the number of MD slaves or
timeouts.
When you say you pushed a message out of quarantine, what exactly did
you do?

Last night I changed the MIN/MAX slaves from 3/5 to 5/10 respectively, setting the BUSY/IDLE timeouts to 60/300 respectively.

After that Milter started failing. This is the section of my maillog as soon as I restarted the whole shebang:

So, this morning I reset my MIN/MAX to 3/8 (from last night's 5/10) and suddenly everything works again. Of the several hundred emails that were queued up from all over the world to be delivered to us, everything came through in a matter of about 20 minutes. MD behaved just fine, informing remote machines when it ran out of slaves, everything worked fine. All email has now been delivered and we're back to our usual trickle of 30+ emails per hour.
