I have seen a few threads about Memory leaks in the COM object
implementation here but from what I see this has never been solved. For
instance this little piece of code proves it:

$excel=new COM("Excel.Application");      	  
for ($i=0;$i<50000;$i++) $excel->sheetsinnewworkbook= "1";
die();

It's not always a property that causes the memory leak. It's also the
method you call when you pass strings to it. Also when you try to
reference a property that does not exist. I'm using my own COM object
to test it with and 5000 cycles o calling a simple 3 string parameter
function uses up to 30MB of RAM.

Please try to fix it. We have to use a CGI mode where every instance of
PHP is freed completely. But we want to use the ISAPI it is not
possible to do that now. Thank you
Jakub
