Zombie Process

Now a Days i am in searching for a solution/culprit of HIGH CPU UTILIZATION of my Oracle ERP (EBS 12) on Operating System Oracle Linux 6.5.
On Top command i can see that zombie process and major zombie process are

root 1404 0.0 0.0 0 0 ? Z May10 0:00 [ps]
root 1520 0.0 0.0 0 0 ? Z 06:48 0:00 [ps]
root 59572 0.0 0.0 0 0 ? Z May10 0:00 [sh]
root 59674 0.0 0.0 0 0 ? Z May10 0:00 [sh]

i ran ps aux

attached is the result.

MY Question is are the Positive Zombies ? Are the reasons for HIGH CPU UTILIZATION.

unlikely because they’re all dead child processes, but it might be a good idea to find out which parent process isn’t cleaning up it’s children

ps -ef | grep 1404
ps -ef | grep 1520
ps -ef | grep 59572
ps -ef | grep 59674

should give you a clue what the parent process(es) are … then (where feasible) just restart the parent process.

If top is showing zero cpu usage, what does “load average” say?

  • if this isn’t low, it sounds like something crashed in the kernel, in which case you’ll need a reboot …

Well CPU is not Zero (Please See Screen Shot as attachment)
