I was getting the following error occasionally. I've search through stackoverflow but all are due to other issue (either cgi or permission) If i can load the following page occassionally (about success 644,000 times in a day and failed 8,000 times.) then I'm sure it's not about permission.

I need to reload the following page stably every 15seconds.

[Sat Aug 01 15:21:03.393569 2020] [core:error] [pid 9328:tid 15760] [client 127.0.0.1:52411] End of script output before headers: index.php, referer: http://127.0.0.1/Admin/index.php?type=14

The following is my apache setting for a 16 core, 32GB cloud instance. Running on windows server 2008 environment + apache 2.4 + PHP 7.0 ONLY. Page reload via chrome + super auto reload plus plugin.

<IfModule mpm_winnt_module>
    MaxConnectionsPerChild 100000
    ThreadsPerChild 1920
</IfModule>

FcgidMaxRequestLen 51200000
KeepAliveTimeout 50
MaxKeepAliveRequests 100
Timeout 600

The script is doing the calculation with PHP and refresh via timeout of JS. JS refresh every 15s and the plugin refresh the entire page every 1 hour. Any advice?

Any errors from PHP itself? I wouldn't know where to find them on Windows. – Gerard H. Pille Aug 01 '20 at 09:22
@GerardH.Pille No error, but miss the execution of script occasionally. – ironman Aug 01 '20 at 09:52
Well, that's Windows. Can't you retry when there is an error? Otherwise you'll have to enable the PHP logging. – Gerard H. Pille Aug 01 '20 at 13:15
