Hi Chun,
The tracebacks are because of the bug CSCth42799. Details are available at
This bug will be fixed in next release of IOS (12.2(58)SE) which is expected in another couple of months. Meanwhile, the workaround is to reload the switch which should stop the logs.
Hope this helps,

Tracebacks can mean either one of two things: Either you have an IOS bug or a hardware failure.
What IOS are you running?
DO you have "crashinfo" file(s)/subdirectories in your switch?

Hi, CSCth42799 is not visible on CCO and the release notes of 12.2(58)SE1 or SE2 do not mention this bug.
Is it fixed in one of this code? Regards Guenther
