Seeing higher than expected IO (Disk writes). At times system can become unresponsive and have to reboot to recover from problem.
Disk write IO is appears at around 200 K/s and as a percentage 15% (using iostat). These processes are httpd.worker -DSSL and there can be many of these
IO should not be so high.
