Do you have any Java process running?
And following up to myself... I see this phenonomon on most hosts that run a java process but I'm still lacking some decent explanation why java would exhibit such behaviour. Any experts?
No Java processes running. Now that I have more info and some sleep, I most recently shut down 3 VMWare instances, they were listed as zombies so I ignored them. This morning I cam back to see:

So I issued a reboot.
It hung on stoping iptables.
I had to power cycle the machine.
