Unresponsive PHP-FPM & chkservd active

Hello guys, I'm facing a issue with a customer's server using latest cPanel + PHP 5.6 + PHP-FPM Handler. Eventually, when a access peak happens, PHP-FPM gets unresponsive and not load the website content. chkservd is enabled to check PHP-FPM service but as I can see, chkservd does not note for php-fpm service fault, maybe the service is active but not responsive. To fix this issue, I have to run /scripts/restartsrv_apache_php_fpm Even using "--check" flag when the website is unresponsive, I get "The 'apache_php_fpm' service passed the check." There's something probably wrong while checking if the service is really UP (and working) Tried to look for php-fpm error logs, but all paths from this doc: The cPanel Log Files - cPanel Knowledge Base - cPanel Documentation Doesn't exists, like this one "/var/cpanel/php-fpm/USER/logs/slow.log" and this one "/var/cpanel/php-fpm/USER/logs/error.log", as you can see: # ls -l /var/cpanel/php-fpm/ total 28 drwxr-x--x. 5 root root 4096 Apr 5 00:16 ./ drwx--x--x. 97 root root 12288 May 12 13:19 ../ drwxr-x---. 3 root cpanelphpmyadmin 4096 Apr 5 00:16 cpanelphpmyadmin/ drwxr-x---. 3 root cpanelphppgadmin 4096 Apr 5 00:16 cpanelphppgadmin/ drwxr-x---. 3 root cpanelroundcube 4096 Apr 5 00:16 The trash way I found to "FIX" this issue was with a cronjob every 30 minutes to check if service is healthy.. if curl -s --head --request GET /dev/null; then echo "Webiste is UP" else echo "Website is DOWN" echo "" | php /scripts/restartsrv_apache_php_fpm fi -------- Is there someone suffering of this kind of issue as well? Any help will be appreciated
