This is a postfix problem, but I think in your postfix
master.cf you
artificially have the smtp process limited to 2.  I think
the default is
100.  From mine:

# service type  private unpriv  chroot  wakeup  maxproc
command + args
#               (yes)   (yes)   (yes)   (never) (100)
#

smtp      inet  n       -       n       -       -      
smtpd

Well, it's pretty obvious I'm floundering here, but I'm
hoping someone
has dealt with this, and can tell me just what kind of idiot
mistake I've
made. I'm getting some nastygrams in my logs, particularly a
bunch of the
first line, and messages are queueing after a very short
period. I'm
obviously setting something up incorrectly, but I just can't
detect it.
Doesn't help that I was here until 01:00 last night fixing
the database
issue.

Thanks,

Kurt


representative log entries (the first one is, I think, the
