Hi all! I have got a Debian 6.0.3 server, with nginx 1.0.11 and php5-fpm 5.3.10. I have a virtualhost using PHPBB. I randomly get Internal Server Error 500 for this virtualhost. There is no trace of any error in nginx error log, nor php-fpm error log, nor php.log. How. where can i find what is causing my problem? Thx. ---

Are you running nginx or php-fpm in a chroot jail? If so, not having all your dependencies inside the chroot can result in strange 500 errors without any log entries. – [Bigdinosaur.org](http://Bigdinosaur.org) Webmaster Sent with Sparrow ([http://www.sparrowmailapp.com/?sig](http://www.sparrowmailapp.com/?sig)) ---

I am not using chroot jail.
