I've been using the ISAPI module (php4isapi.dll) for a while, and it seems that the module from 4.1.2 is much more stable than the one from 4.2.1 Most crashes happen with big scripts, like phpmyadmin. php gives than an acces violation. Sometimes it's enough to wait untill all connections are closed, but in most cases, IIS has to restart. However, ASP and other ISAPI modules haven't crashed, so the php ISAPI module doesn't affect any other modules, despite what's told in the readme.

Thank you for your interest in PHP.


We really need more information to be able to do anything with this. We know the ISAPI module is less stable then the Unix stuff, and that\'s because there are very little developers checking this out.

Can you provide a minimal sample script that causes it to crash consistently?  What PHP modules are you using?  Have you tried using the low security setting?  See bug 15333.

I have the same probleme with a Windows XP.NET, IIS and SQL server 2000. In a phpBB forum... No bug with the CGI filter... but it is more slow...
