In http error log:

	httpd in free(): warning: page is already free.

Displayed to browser:

	Fatal error: Allowed memory size of 9437184 bytes exhausted (tried to allocate 1144 bytes)

One or more apache server processes become unstable and unable
to handle more requests.  Result is a page that "contains no data" being
sent to the client.  The problem seems to appear on machines that
serve w/session usage.  Not repeatable in a predictable manner.

I am certain it is a problem with PHP because If I change the max-memory
value in PHP.INI the value produced in the error (above) increases.

Apache version .1.3.20, with mysql support, imap support and ldap
support.   Both compiled statically and as a dynamic module.

We are actively using Mysql and sessions on both affected machines.
