High CPU Usage

[Eusk]

I have 4 omniswitch 6850 working in stack. One of them has a high CPU usage (92 %). I would like to know what is causing this high usage in stackmember 4.

I am running 6.4.4.343.R01 GA, June 23, 2011.

show running-directory: Current CMM slot :2. It asks me for the credentials when telnet to the stackmember 2(127.2.2.1) and 3(127.2.3.1) whereas the 1(127.2.1.1) and 4(127.2.4.1) directly access the kernel.

I have noticed that the ping to each of these IP addresses(127.2.x.1) takes about 1 ms, except for the stackmember4, which is quite superior (61.53,81, 4,110 .. ms). I don't know if it can be related.

Thanks
