I have a stack of Summit 450 and 460 switches. All are running XOS 12.6.2.10 (I know it's old, but we don't pay support so can't upgrade). We regularly have a situation where the management interface (SSH or Telnet) is slow to respond. Traffic does not appear to be affected in any way. Top shows the bcmDPC process is using 60 to 70% of the CPU when this happens. It seems like it started when we expanded the stack from 3 to 4 switches about 6 months ago.
Anyone have any thoughts on what bcmDPC is and what might trigger it to use so much CPU?

'k, thanks. I've been avoiding the reboot of the slot due to the interruption to services, but perhaps the time has come.

Temp solution would be to reboot the slot/stack
