Are you using <Perl> sections anywhere?

There is a (very) long thread (on the dev list) starting here:

relating to a "Free to wrong pool" error when using <Perl> sections.

The following short httpd.conf file demonstrates the problem in that thread:

LoadModule   perl_module C:\Temp\modperl-2.0\src\modules\perl\
ServerName   localhost:8529
Listen       8529
ServerRoot   C:/Temp/modperl-2.0/t
DocumentRoot C:/Temp/modperl-2.0/t/htdocs
LogLevel     debug
Listen       8530
<VirtualHost _default_:8530>
  PerlSwitches -IC:/Temp/modperl-2.0/Apache-Test/lib
  PerlSwitches -IC:/Temp/modperl-2.0/blib/lib
  PerlSwitches -IC:/Temp/modperl-2.0/blib/arch
  PerlOptions  +Parent
  <Perl >

In our case, the server won't even start.  In fact, even running 
apache.exe with the "-t" switch (syntax check) crashes it.  Just 
commenting out the "<Perl>1;</Perl>" bit prevents the server from crashing.

Your problem is obviously different since you've got your server 
running, but maybe it's related?
