Short reproducable scripts are fine. Please leave the status at
"feedback" until you can provide those.

I'm guessing you're looking for the PHP scripts that are being used in
this performance test. I'm working on getting this. If you need
anything other than the scripts please let me know.

It's possible if you provide some more information about the issue. The
patch would be good too.

We are currently unable to use PHP 5 with our application.

Any chance this memory leak will be fixed in an upcoming PHP 4.x
snapshot?

Please try using this CVS snapshot:

  http://snaps.php.net/php5.1-latest.tar.gz
 
For Windows:

Description:
------------
Latest 4.x snapshot has memory leaks in php4ts.dll.

Here is the output from the debugger:
---------------------------------------------------
php4ts.dll is responsible for 45.47 MBytes worth of outstanding
allocations (92% Leak Probability). The following are the top 2 memory
consuming functions:

php4ts!XmlParseXmlDecl+9d: 21.43 MBytes worth of outstanding
allocations.
php4ts!XmlParseXmlDecl+fb: 13.86 MBytes worth of outstanding
allocations.
---------------------------------------------------

We are running performance tests against W2K/IIS5 in ISAPI mode. Very
simple PHP scripts which open a connection to Oracle thru ODBC. These
performance test run without issue in CGI mode but the CPU performance
is unacceptable so we are trying to get ISAPI working.
