3550 Switch Process-related Question

My 3550 Switch shows a "show process cpu" result like below.

Please pay attention to the 33th process and its utilization.

LGT_MAIN_3550_B# sh proc c

CPU utilization for five seconds: 100%/0%; one minute: 99%; five minutes: 99%

Re: 3550 Switch Process-related Question

What software version are you running? Take a look at the following bug

http://www.cisco.com/cgi-bin/bugtool/onebug.pl?bugid=CSCdx31480

12.1(11)EA1a should be a good code to run
