6 controllers hooked up to a router - these are m3 controllers. Suddenly SNMP warnings come through saying multiple controllers are at critical network process load.
One of the controllers appears to be very sluggish over SSH and HTTP. I reboot it - router instantly calms down. Show cpuload and cpuload current show everything low. Show processes show everything is okay. Only thing that is wack is:

while on the other 3 controllers have CPU 17 around 99%.
Any tips or ideas?
Nothing is crashing so no logs there but I did pull tech-support logs to send to TAC.... just wanted to poke around a bit still before I open a case....
Thanks!
