Apache on WampServer Keeps Crashing

I run a medium traffic website that seems to be crashing all the time and I have to restart because it either doesn't load or cloudflare displays 520 error.

Anyway I have searched up this error and they say to enable KeepAlive, but I haven't seen that option in the httpd.conf.

My server info ( Yes I know linux is useful but I am using many windows softwares on my server computer as well ). I am running apache that is integrated with wamp server.

8GB of RAM and i7-2600, so it's a fast enough server.

Fast enough Bandwidth as well.

Here is the error log, let me know if you need any more info, thank you!

You could try these parameters in your httpd.conf file. It has helped with this sort of situation in the past and it may help yours.
