Im running a php script with ioncube/zend.
All Cores are at 100% and the system begins to accumulate load.
All httpd processes are in R (reading status) and it looks like they are reading on something. I have to restart apache to fix the problem temporarily.
also domain.com/server-status does not show any php script with high cpu usage.
PHP 5.6.29 (cli)
Ioncube loader version 6.0.8
