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:
[Fri Jun 30 10:49:29.817548 2017] [lsapi:error] [pid 3341:tid 139899021747968] [host www.domain.com ] Backend error on sending request(POST /wp-cron.php?doing_wp_cron=1498844968.7457189559936523437500 HTTP/1.1); uri(/
