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: 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.
