HP 2910al CPU spike due to 'Debug & Test' process
Things that make you go hmmm....
Last night our Cacti monitoring system sent out a bunch of warnings regarding the CPU usage on our HP ProCurve 2910al switch. The CPU utilization climbed to nearly 100%, and was well above 50% for a few hours. This had never occurred before.
I logged onto the switch to discover what process was sucking up so much CPU.

% CPU | Description

9.5 | Idle
90.5 | Debug & Test
Interesting. My Google searches found nothing valuable, other than this had occurred to other people too. No authoritative information seems to be out there. If it happens again I'll make a call out our HP rep.
