Sorry for the unhelpful title, but the PHP ISAPI filter dies, leaving the below messages in the logs.

One page would not load, and then subsequent pages were "PHP has encountered an Access Violation at 77FCB2A7".

The page always loads fast - all it does are a couple of MS SQL queries via an abstraction library (namdal-ms.php). open_database() calls mssql_pconnect()

Application protection is "Low" as recommended in bug #15333.


PHP error log:

[24-Apr-2002 10:21:54] PHP Fatal error:  Cannot redeclare open_database() (previously declared in namdal-ms.php:39) in namdal-ms.php on line 38
[24-Apr-2002 10:22:16] PHP Fatal error:  Maximum execution time of 30 seconds exceeded in namdal-ms.php on line 68

Loaded modules are php_mssql.dll and php_socket.dll

Under the Home Directory tab, clicking "Unload" will return things to normal.

As this appears to be a flaw in the memory management, would unticking "Cache ISAPI Applications" help?

That is the most common problem with the ISAPI filter of PHP.

I would just run it as CGI.
