periodic bursts

Hello all,
My realtime system experiences periodic bursts every 4 hours. How can i find the reason for this  ? I know the traceit tool but it dumps so much data and it is useless under this case. I need to find what happened at the exact time of burst.

I use rtai_smi module to disable SMI interrupts and set my network interface driver priorities to 99. So it should be something non maskable but what ?

Sinan.
