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:


top - 09:48:56 up 146 days, 14:22,  2 users,  load average: 3.00, 3.00, 3.00
Tasks: 105 total,   1 running, 101 sleeping,   0 stopped,   3 zombie
Cpu(s):  0.0% us,  0.0% sy,  0.0% ni, 99.7% id,  0.0% wa,  0.2% hi,  0.0% si
Mem:   1928300k total,  1911376k used,    16924k free,   182208k buffers
Swap:  2031608k total,      224k used,  2031384k free,  1139440k cached

So I issued a reboot.

It hung on stoping iptables.

I had to power cycle the machine.
