sles9 ps issue -threads/children show no usage.

Since this list was so helpful last time, Thanks to everyone that replied. I seem to be having another issue, it seems when I run a multithreaded app the when you look at it with ps it doesn't report the cpu usage for any of the threads. The parent process ramps up at startup, but goes to 0 while running, and when you stop the process the parent ramps up, while all of the children stay at 0. These are our load tests so they should be showing some sort of information, considering that they really hammer the box. Has anyone seen anything like this before ? Any help would be great .. /rod
