Travis: Initiating build for commit 'ab6070fca5de90d1b645ae95a54e18a0c82f4be0' on branch 'master': refs #4439 disable eAccelerator if enabled (just disabling optimizing did not work) and display a message in the admin UI. Also disabled eAccelerator during tracking. We might need to move the method to detect eAccelerator to another place, not sure if this is the best one
