[users@httpd] 500 Internal Server Error with no log entries

[Mohammad Aghanabi <m....@gmail.com>]

I'm running Apache v2.4.27 X64 for serving PHP files and it was running
fine until today that I'm seeing `500 Internal Server Error`.

Surprisingly nothing noticeable is logged neither in PHP error log file nor
Apache's. I attempted to set `LogLevel warn trace8` and found this:


[Wed Jan 23 12:06:58.344368 2019] [fcgid:warn] [pid 13700:tid 1180] (OS
109)The pipe has been ended.  : [client 127.0.0.1:54040] mod_fcgid: get
overlap result error
[Wed Jan 23 12:06:58.344368 2019] [core:error] [pid 13700:tid 1180] [client
127.0.0.1:54040] End of script output before headers: index.php

But I can't realize where I should look for the problem.
What can I do to debug this?

Thanks

report above. then either upgrade or downgrade.
