Exact reason for CL site errors in apache error log
I really need the ability to have the apache error log to show the exact reason why a service unavailable error or 503 resource error occurred. This will make troubleshooting these errors, which some of our accounts are getting a lot of, quick and easy and we wont have to open up support tickets each time. For example all we get is below, which doesnt tell us much at all:
[Thu Jun 29 17:56:28.980083 2017] [lsapi:error] [pid 9869:tid 140474580313856] [host domain.com] Error receiving response: ReceiveResponse: receive pkg hdr failed: ReceivePkgHdr: nothing to read from backend socket.

Or I get errors like which are cryptic as well:
