1.6.2 Beta Build - Insane CPU Usage Easiest Way to Debug??

I'm receiving insane amounts of CPU usage on my server with only about 22 people in it.

http://puu.sh/3TKF6.png - Shows where it normally goes to.

Specs:
E3-1240 v2
32GB DDR3 1333Mhz
Intel 520 SSD x2 In RAID 0
CentOS 6.4

Plugins: http://puu.sh/3TKJY.png

You can see some custom plugins in there, I HAVE tried taking out my custom coded plugins, still the CPU goes insane. All plugins are updated as much as they can be.

necrohhh Please bump only once every 24 hours. Also, WarmRoast is a GREAT program to help you figure out why your server is lagging. Brought to you by the same developer who made WorldEdit and WorldGuard.

 

Sorry For the bump. Very anxious to get this figured out.

This program is e.p.i.c it lead me to my issue. Now, the only issue is that its very hard to pinpoint EXACTLY what it is.

I deleted all unnecessary worlds, and lowered my mob limit a TREMENDOUS amount. Still looking a bit high?

Any more suggestions?

EDIT:

Here is a full read from WarmRoast in what appears to be the affected areas.

Minecraft have a bug with zombie's pathfinding.
Something with finding a path to village doors or what.
I have the same issue too.

 

Well that's good to hear. I was afraid I was alone on this one =/ Is it known? If not we need to let them know about this, it's extremely terrible. Servers with over 20 people I don't even understand how they are functional!?

 

Yes i can't understand that too =S
However they know about this: https://mojang.atlassian.net/browse/MC-17630
