Odd Server Error mod_fcgid

[mediasnog]

This is a totally new one for me. This error only happens when certain threads are viewed...

mod_fcgid: stderr: die 4 false, referer: http://www.xxx.com/showthread.php/19510

I've hunted for any similarities in the threads and cant' seem to find anything that is common between them.

The odd thing is if I turn the site off in the control panel, those type of errors go away.

I have tried disabling all mods, disabling the plugin system with no success. The error is always generated.

I have also tried a suspect file version check and all is the way it should be.

Any ideas about what might be causing this would be welcome.

Enable display_errors in php.ini & restart apache/nginx etc, then view those certain threads/posts and see if your presented with a error.

Thanks for the idea, but I already tried that. I even set all errors to be displayed in global.php to be sure it didn't get overridden by vB.

Nothing comes up on screen.
