Re: dspam problem

[Paul Goyette <paul%whooppee.com@localhost>]

Interesting...

I've noticed that as long as dspam only processes one message at a time, 
things seem to be OK.  But as soon as it has more than one thing to do, 
there's a good chance that the process will just die.  (I haven't gotten 
as far as you have to identify the exit reason.)

I've got a little cron job that runs every once in a while and checks to 
see if dspam is down.  If it is, I restart dspam, and then go through my 
mailq and run postqueue -i for each entry in the queue, with a short 
sleep after each requeue.
