| Hello,
You will also need to turn off mod_php if it’s loaded.

If you can, I would upgrade to httpd 2.4.x... If you must stay w/ 2.2.x, then Worker might be more reliable for you than Event. On Mar 1, 2017, at 9:56 AM, Jayaram Ponnusamy <jayaram.ponnusamy@xxxxxxxxx> wrote:
Thanks Jim for the suggestion.
I will update
Timeout 5
KeepAliveTimeout 2
We are using Apache 2.2.23
We will try to install Event MPM and will check.
Thanks
Jay

You should not be using prefork unless you really, really need to.
Assuming you are running 2.4.x, I would strongly suggest running
the Event MPM.
Your Timeout and KeepAliveTimeout values are also way too big;
I'd recommend 5 and 2, respectively.
