Jigsaw a3 hanging

I've been having problems with Jigsaw when my site is getting
many simultaneous hits - specifically to CGI stuff (this is
on Solaris 2.5).

Jigsaw starts a new process so that I have two Jigsaw's running
at the same time.  Then when I try to access the site, the 
server hangs indefinitely.  I've tried killing the process with
the higher PID number, but that doesn't seem to help.  Also,
I can't get to the Admin pages to restart under these conditions.

Any ideas on how to deal with this?
Thank you.
