php5isapi.dll (5.1.2) - IIS5.1 issues

Hi there,

I've been running a website for quite a time on using PHP 5.1.1 (php5-cgi.exe) without any bigger problems. Recently some timeouts while requesting a webservice lead to heavy memory and processor usage (spawning too many php5-cgi.exe processes). The problem fixed, I read about the ISAPI module and that it would be faster and more resource saving. That lead me to exchange the cgi and do an upgrade to php5isapi.dll version 5.1.2.

I followed the installation instructions closely and afterwards everything seemed to work - The server reacted faster and I thought that everything would be fine. But the ISAPI started to act strangely. I am using PHP just to include some files and grab some data from a db - not really a heavy usage. But it seems that the ISAPI keeps crashing the whole IIS after some time. Only a reboot is able to fix this problem. The application event-log doesn't help very much as it contains no traceable entry to the problem.

Has anybody encountered such a problem using php5isapi 5.1.2 with IIS 5.1 ?

Thanks in advance!

so long,

Borgond
