Hi I have several hundred 5420 switches running Switch Engine and x435s running EXOS code 32.7.1.9-patch1-68. They are all monitored via XIQ-SE and have the standard CPU alarm configured. From time to time this alarm triggers but then checking CPU on CLI everything is ok. Once the hal process was pegged at 99% but for the rest of times everything seemed normal. Is this a software defect? Some 5420s are stacked and the issue seems more common there.
