I've just upgraded from 6.1.1 E2 to 6.2.1 E3 and the CPU usage has jumped from 43% to almost 100% constantly. The sig has changed from 340 to 369, but everything else is the same on the unit. Has anyone else found this?
We had the same issue going from 6.0(5)E2 to E3 on all machines. Basically sensorapp utilizes more CPU cycles, I believe, making the CPU stat fairly meaningless. There is a load statistic that more accurately refects whats going on in 6.1.X and 6.2
