Responsive system/High load average and hanging ps
I have a server running kernel...
2.6.8-24.14-smp #1 SMP Tue Mar 29 09:27:43 UTC 2005 x86_64 x86_64 x86_64 GNU/Linux
This server runs intense java build services (using maven).
What I am seeing is after a short while of booting, the machine starts getting a high load average (the highest I have seen is 3600).
However, the machine is still responsive.
When I do a ps -ef (or find through /proc) the command hangs (and cannot be terminated).
The only way to reboot is to pull the power.
Does this sound familiar to anyone? How can I diagnose?
