Re: Who can told me why?

What IOS version is running on this device and what model is this?. Is this devie is being polled by CW2000 RME application?

Re: Who can told me why?

This is message from CISCO Error Message Decoder..I hope this help..

1. %SYS-3-CPUHOG: Task ran for [dec] msec ([dec]/[dec]), process = [chars], PC = [hex].

The indicated process has run for too long a period of time without relinquishing the processor. The process is a "CPU hog."

Recommended Action: If this message appears during startup or during OIR of a card, no action is required. If this message appears when accessing a Flash memory device, consider replacing the affected Flash memory device. If this message occurs during normal router operation, it is most probably caused by a software failure. To take advantage of recent fixes, upgrade your system to the latest Cisco IOS software release in your release train.

Re: Who can told me why?

First CPU hogs are always bugs. I would open a TAC case for this. Second, I would examine my configuration carefully for ant issues with the way this box is configured. For instance, if I had to guess, I'd guess that you have a large route or a default route staticlaly configured to some sort of a broadcast interface. For instance, you might have:

ip route ethernet 0

This would be a bad thing, since the router must send an arp request for each reachable destination on the ethernet 0 interface, and this will take a lot of processing time and memory. You should always configure statics across a broadcast interface to a next hop, rather than to the interface, if at all possible.
