Hi,

I was getting Out of Memory PHP fatal errors on my Apache 2.2.4 server
on WinXP and narrowed things down to discover that httpd process
memory is not released after a PHP script is requested (even the very
most basic script: <?php ?> ). The httpd memory usage increases
approximately 520k after every request (if the request occurs after
the KeepAliveTimeout period.

I imagine that there must be a straightforward reason for this, but I
can't figure it out. I've looked through my php.ini and httpd.conf
settings and nothing is obvious. The behaviour occurs with PHP 5.2.2
and 5.2.4.

Any suggestions?

I've narrowed the issue down further but I'm still stuck. Even with
the php5_module not loaded in apache, memory is not released from the
httpd process after a simple html page request (about 110M retained)
each time. I'm using taskmgr to monitor this.

The problem seems to be related to a specific machine (a different
machine with a similar configuration (Apache 2.2.4, PHP 5.2.4, WinXP)
does not exhibit this behaviour. Since this seems to be an OS problem,
what techniques could be used to troubleshoot?

Thanks.
