Script timed out before returning headers

Hi, I am referring to this very very old thread: http://forums.cpanel.net/f5/script-timed-out-before-returning-headers-206601.html This is a very old post but for anybody with the same issue, the solution worked for my situation. When installing vtigercrm6.2.0 I got the same error usually after +-15min. Setting my Apache Timeout to 1200 (20 min) solved that.
