Thank you.  I appreciate the suggestion.

OK.  I want to help.  Can you steer me to documentation that explains
how "feeding back the crashes" takes place?

Can you steer me to documentation on how to setup a system to auto
reboot after a panic?

I'm using Solaris 8 Intel for now.

I would like to see these perceived short comings overcome.  I prefer
to spend my extra time on NetBSD rather than Linux.  I assume Tomcat 4
is not the high risk area.  Oracle is the likely problem area.  What
can I do to help advance the cause and ease your pain?
