[c-nsp] Cisco WS-C3560G-24TS-S Port Mirring Issue

[Chris Gotstein]

I have a WS-C3560G-24TS-S running 15.0(1)SE2.  I have a simple port 
mirror setup to mirror traffic from gi0/1 to gi0/2:

monitor session 1 source interface Gi0/1
monitor session 1 destination interface Gi0/2

Over the course of last couple months, the monitor session stops 
working.  If I remove the above commands and reenter them with a new 
session number, the mirror comes back up.  This has happened about a 
dozen times so far.  Is there a known bug in the code?  Could the 
equipment that is plugged into gi0/2 cause problems and break the 
monitor session?  Any suggestions appreciated.  Thanks,
