Maybe a conn_rec was created by the custom module and allocated from the wrong
pool?

At any rate this is apparently not an httpd bug.

Unclear.  The problem doesn't occur without the custom code, and others
probably won't have that custom code.

If you find out the root cause (exactly what in the custom module led to the
problem), update the bug in case it can help others.
