CPU spikes on CSS

Is there anyway to diagnose cpu spikes on the CSS or possibly decipher the output from the "cpu hog" debug?

Thanks

the cpu hog tells you what processes hold the cpu in the last cycles.

You have to capture several times the command and see if the same process comes all the time.

Knowing the process is not very useful unless you know what it does. Most of the times the process name is not explicit enough.

So, I would recommend to either give us the cpu hog or open a TAC case and let a TAC engineer check the cpu.

There is also a different way to capture the cpu processes.

It requires some special commands [spyReport] and to load the symbol-table before the CPU spikes.

Regards,

Gilles.

Gilles,

Thanks for the response. I'll try to capture a series of outputs from the cpu hog when we see it spike.

thanks

Simon
