create child process failed. Exiting.

["aqua" <suppressed>]

Dear group.

I am using Windows 2000 server with Apache 2.0.59 with mod perl 2.0 and Perl 5.8.8  and using few CGI scripts in PerlRun mode.
===========
Alias /cgi-bin/ "D:/Apache2/cgi-bin/"
<Location /cgi-bin>
   SetHandler perl-script
   PerlResponseHandler ModPerl::PerlRun
   PerlOptions +ParseHeaders
   Options +ExecCGI
</Location>
===========

Now and then my apache exiting and I would like to know 

1. What is the reason for this error or how do I know because of which script my Apache is exiting
2. How do I restart my apache automatically.

Appreciate any pointer in this regard.

Regards
Dominic
