ASA 5520 Interface Frequently Reset.

The interface G0/1 of our ASA5520 has a large number of interface resets when issue show interface command. This number increase every several minutes. Other interfaces are ok.

I am very sure there is no cable and patching problems, because I have test cable with another box.

When the interface reset, I can not ping it. After several missing pings, it recovers to normal.

Please anybody knows it is hardware or software problem?

My software version: 7.2(2)33.

Many thanks.
