    I have a server where I was using PHP-FPM with worker MPM, however recently traffic grew a bit and I found that server is almost non-responsive, on checking found couple of PHP-FPM process using 100% cpu . Tried adjust pool value etc. But no gain, then I switched to cgi handler for PHP and now server can handle that increase traffic without lockup.

    Meanwhile, apache error logs is showing following error with php-fpm
    [mpm_worker:error] [pid 31494:tid 139998474065888] AH00288: scoreboard is full, not at MaxRequestWorkers

    However, switching to PHP-CGI , error is gone. Regarding scoreboard full error, most of the people faced error with event-mpm and that too because of some bug in apache which was supposed to be fixed with 2.4.25 .

    In my cpanel I
    Server version: Apache/2.4.27 (cPanel)

    Any idea if I want to use PHP-FPM , what things I need to fix considering the errors I am seeing ?
