Zombie Hazard!
There are a lot of zombie processes and keep increasing. It was once more than 5000 before the kernel was upgraded and rebooted. However after the server reboot the same problem happened again.
Other than that, process "init" is taking 100% of CPU and causing high load.
Server specs is as below:
Dual Xeon 2.80 w/ HT
2GB RAM
CentOS 3.3 (kernel v2.4.29)
cPanel
Here is the copy of "top"
