Hi,
I have an infinite loop in my huge application/kernel module i.e. either in kernel or application that boost up CPU utilization to 100%. I have an application that reads multicast UDP packet, process it and send it to the peripheral device on PCI interface.
my guess: either you don't yield yourself at certain amount of data, or you simply forgot to enable the interrupt again when you previously disable it... thus disallowing practically anything to interrupt your way...
I need to know the best approach or tool to debug the infinite loop.
maybe oprofile... -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
