I have a production server, where I am not able to kill php-fpm processes.

I am not able to kill any of the following process with kill -9.

service php-fpm start,keeps on running, but doesnt give any error or output.

System Reboot is not an option :(

[root@vtermination etc]# ps aux | grep "php"
