Php-fpm keeps locking up

PHPphp-fpm

For some reason, php-fpm keeps locking up and/or hanging. It works for a little while, and then it will randomly just 'hang' for a long time upon trying to load a webpage. There's absolutely nothing in my php-fpm.log about it, and I have no idea how to track down the problem otherwise. Can you guys help me track it down by pointing me in a new direction?

CentOS 6.2

[root@3AC19 ~]# php-fpm -v    
PHP 5.3.9 (fpm-fcgi) (built: Jul  5 2012 04:04:34)

Try to profile the hung php-fpm process using strace -p <PID_of_php-fpm process>. You can also try to get stacktrace samples using gdb, more details here.

Nginx – How to restart php-fpm

Note: prepend sudo if not root

Using SysV Init scripts directly:

/etc/init.d/php-fpm restart    # typical
/etc/init.d/php5-fpm restart   # debian-style
/etc/init.d/php7.0-fpm restart # debian-style PHP 7

Using service wrapper script

service php-fpm restart    # typical
service php5-fpm restart   # debian-style
service php7.0-fpm restart # debian-style PHP 7

Using Upstart (e.g. ubuntu):

restart php7.0-fpm         # typical (ubuntu is debian-based) PHP 7
restart php5-fpm           # typical (ubuntu is debian-based)
restart php-fpm            # uncommon

Using systemd (newer servers):

systemctl restart php-fpm.service    # typical
systemctl restart php5-fpm.service   # uncommon
systemctl restart php7.0-fpm.service # uncommon PHP 7

Or whatever the equivalent is on your system.
