PHP Problem With APC

#1
Hello,

I have been migrating my webserver over from lighttpd to LiteSpeed (Standard Edition) and have encountered a problem with at least one site on the server. Whenever I try to access a PHP page served by LiteSpeed with APC turned on, it shows up as a blank page. There are no PHP errors to go with it at all. I have checked. I can find no errors in the server error log that are related. As soon as I remove the APC extension from the php.ini file, it works as expected.

Some notes:
This only happens for one site that I have seen so far.
It does not happen to everyone - many people are still able to get to the site, but some are not (could be a caching issue).
I had APC on my lighttpd install (which is still live for now, though I have removed APC from it in case of conflict).
The APC PHP page (apc.php) DOES work with LiteSpeed and APC turned on and it appears that caching is happening.
The extension is not missing because I have Suhosin configured as well in the same extension directory and it works fine.

Things I have tried:
Recompiling PHP through LiteSpeed.
Turning off APC on the lighttpd install.
Google

Obviously nothing has worked or I would not be here. :p Any advice?

I can access a phpinfo page while APC is turned on and it shows the APC configuration. People who are getting the blank page, however, cannot see anything that needs PHP to execute (they can still see static files, however).

PHP version: 5.3.2
APC version: 3.1.3p1
