Slow delivery of large message

[Monte Mitzelfelt]

I've got a fairly large (45k+ message) being sent to a mailing list of
about 1100 people.  It is getting "qmail-spawn unable to create pipe" 
errors each time the message hits the delivery stage.  At this point, I
also can't seem to ALRM it into sending for some reason.  It is running on
Solaris 7 (SunOS 5.7 is what uname -a reports anyway).

Anybody have any ideas about what I can do?  I've got some irritated
customers I need to help as soon as I can.
