PHP-FPM Segfaults

Hi,
My server is running CentOS 7 and Nginx. All my sites are down and I'm seeing the following error in my Lish console and logs:
php-fpm[7481]: segfault at 1000721 ip 000055e06b693a27 sp 00007ffe89fa6d70 error 4 in php-fpm[55e06b41f000+3d0000]
php-fpm[18551]: segfault at 7f0000000020 ip 000055e06b693a27 sp 00007ffe89fa6d70 error 4 in php-fpm[55e06b41f000+3d0000]
php-fpm[7578]: segfault at 1000721 ip 00005646ea4f4a27 sp 00007ffff87177c0 error 4 in php-fpm[5646ea280000+3d0000]
Help!

Hi,
You can try restarting php-fpm and nginx to bring your sites backup, however, this may only be a temporary solution:
sudo systemctl restart php*-fpm
sudo systemctl restart nginx
You'll want to further investigate these messages to resolve the issue permanently. Your /var/log/kern.log, /var/log/nginx/error_log, and /var/log/php* logs should contain more information. There is a great walkthrough here from someone who saw similar segfaults:
