Php – Lighttpd / PHP-CGI will crash without warning

I'm using Lighttpd / PHP-CGI on a Windows XP machine.

I was using the normal CGI interface which is very stable, but I tried FastCGI and I love the speed boost. However, even under light load, the PHP-CGI daemon will just crash after an hour or so.

I've taken care to eliminate all warnings and notices that get pushed to the error log. My server has about 1500MB excess RAM when it crashes, so that's not the issue.

Just by visiting the site and holding down F5 for about 30 seconds will crash PHP-CGI with a blank error log. Does anyone know what could be causing this? Is there any additional error reporting that I could use, or any gotchya's I'm unaware of?

php.ini:

;NOTE: THE ONLY LINE THAT'S NOT DEFAULT TO php.ini-production IS "error_log = F:/php_errors.log"

Edit: I just tried holding down F5 with the only script running being <?PHP die("alive"); ?> and PHP is still crashing.
