    PHP is segfaulting and hitting it's limits with your specific php web application so you need to debug your php server. What are segfaults = Why Does The Segmentation Fault Occur on Linux / UNIX Systems?

    Examples with strace below:
    With gdb backtrace and PHP debug compiled mode where centmin.sh has a PHPDEBUGMODE variable which you can set to PHPDEBUGMODE=y and recompile php via centmin.sh menu option 5 to enable debug mode for PHP-FPM. After troubleshooting set PHPDEBUGMODE=n and recompile php via centmin.sh menu option 5 again to disable debug mode.
    Code:
    PHPDEBUGMODE=n # --enable-debug PHP compile flag
    Centmin Mod is provide as is, so short of scripted related bugs or issues, any further optimisation to the web stack components - nginx, php-fpm, mariadb mysql, csf firewall etc or web app specific configurations are left to the Centmin Mod user to deal with. So I do not provide any free support for such.

    You'll need to tune your PHP-FPM settings and this is left up to end user to do but here's a thread for starters to enable php status page output outlined at PHP-FPM - CentminMod.com LEMP Nginx web stack for CentOS and PHP-FPM - pm.max_children | Centmin Mod Community which outlines the official PHP-FPM config documentation as well.
