What is this Cisco process?

[joe at gonetforward.com (Joe Renwick)]

So thanks to all for the help.  It was an SFP.  Here is CPU with bad SFP:

   plf-access#

plf-access#sh proc cpu sorted

CPU utilization for five seconds: 11%/0%; one minute: 18%; five minutes: 21%

 PID Runtime(ms)   Invoked      uSecs   5Sec   1Min   5Min TTY Process

  41   237737055   1095169     217078  5.11% 11.74% 14.87%   0 SFF8472

Here is CPU with SFP taken out:

   plf-access#sh proc cpu sorted

CPU utilization for five seconds: 5%/0%; one minute: 17%; five minutes: 21%

 PID Runtime(ms)   Invoked      uSecs   5Sec   1Min   5Min TTY Process

 106         322       437        736  0.79%  0.07%  0.03%   0 Exec


Confirmed it was the SFP by pulling it in and out a couple times.  Processor
flapped right along.


Thanks again to all,


Joe

that includes diagnosting monitoring of SFPs..."
