I attached the output. The CPU usage wasn't high. We are ISP. The router works as gateway to our customers. The throught is 10Mbits/s max. There is not inter-vlan routing.
This morning, the router stopped working. The *Dead* memory pretty high. Is this memory leak issue?
After reloading router, the router works fine now.
