What are these queues and what is the significance of drops in any of these queues? On some of our switch stacks queue 3 and queue 8 have some drops.

"show controllers cpu-interface" gives the names of the queues.
For example Queue 0 is used for RPC, Queue1 is used for STP and so on..
Here is the relevant output of the command :

How or when are these queues used? Where is traffic coming from or going to when it passes through these queues?
