Project Description:
He contratado un servidor dedicado para alojar una web en drupal. Cuando ejecuto cualquier script que dure mas de 45 segundos retorna un error:

"An AJAX HTTP error occurred. HTTP Result Code: 500 Debugging information follows. Path: /?q=batch&id=11&op=do StatusText: Internal Server Error ResponseText: 500 Internal Server Error Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator to inform of the time the error occurred and of anything you might have done that may have caused the error. More information about this error may be available in the server error log."

Esto en configuración fast cgi porque si cambio a cgi retorna un error 504.
El servidor esta con instalación Ubuntu 12.04 LTS 64bit + Plesk 11.0
Necesito alguna persona que dandole acceso al servidor me pueda indicar y añadir los parametros para aumentar el tiempo de ejecución de los scripts y así funcione drupal correctamente.
