Description:
------------
I'm running Vista/Apache2.2.8/PHP5.2.5 with PHP as mod_php rather than as a CGI. Apache2 was installed using the msiexec /i flag as described here: www.simonwhatley.co.uk/installing-apache-on-vista .

The include_path set in a vhost basically just gets 'forgotten' after a while and the value set in the specified php.ini gets used. As a result, applications fail because they can't find the files intended to be included, with the result:

Warning: require_once(app.php) [function.require-once]: failed to open stream: No such file or directory in C:\Users\Tallyce\Documents\Website1\launcher.php on line 12

Fatal error: require_once() [function.require]: Failed opening required 'app.php' (include_path='.;C:\Program Files\php\pear;C:\PROGRA~1\php\pear') in C:\Users\Tallyce\Documents\Website1\launcher.php on line 12

(so PHP is still running, just not looking in the right place any more.)

Restarting apache's 'Restart' link on the start menu using right-click > 'Run as Administrator' fixes the problem, until it happens again.

Different vhosts seem to lose the setting at different times.

The problem seems to happen more often when other sites' pages are loaded more often. About 20 page loads are sometimes enough to cause the problem to happen again.

The problem started after starting to use Vista rather than XP as before.


I've tried running Process Monitor from sysinternals, and limiting the results to httpd.exe . I notice that the following output does not always appear, though before this point the output is consistent (though I've no idea if this is relevant). After this point, the output changes to reflect the different include_paths being checked.

A diff of phpinfo output in the incorrect state, vs. the post-restarted state is:
