You can rconsole the MP (and/or LP's) and run the "debug packet capture" command. This will show you packets hitting the CPU on the module. The default output is 25 packets. Running a "show cpu lp" will also show CPU usage on the individual LP's which may make it easier to single out the source of the CPU increase.

Hi list,

We are running a few XMR's in our network where one of them is showing
increased CPU usage on ip_rx. The box is not doing enormous amounts of
traffic (<10Gig) and a similar configuration on a different part of the
network isn't showing any CPU usage problems.
What is the best way to debug CPU issues like this and how can i get a
better insight in the way an XMR uses CPU cycles? A "show cpu" and "show
tasks" shows me what i already know and now i find it very hard to debug.

Any ideas?
