we got one ips 4270 sensor.one of the cpu always overload(over 95% in the IME soft),but when i use the command "show statistics virtual-sensor | in processing load percentage" to check the cpu usage rate.it's under 5.
sometimes the sensor will hang,then i have to reload it..TAC suggest upgrading the image from 6.x to 7.x..but in fact ,there is no change.
Starting with the E3 engine update, the IPS uses a different algorithm for managing its idle time, and spends more time polling for packets to reduce latency. This results in the higher CPU usage being reported than previous releases, including output by external tools such as top and ps. This additional CPU load can be noticed on all Intel-based platforms, single-CPU platforms as well as the primary CPU of multi-core models. (AIM and NME-IPS already show 100% CPU usage on the primary core, regardless of load, on all releases.) So the high CPU is normal.
Do you still have a TAC case open for the hang issue? What code are you currently running?
Please feel free to email me directly if you would like to work through a TAC case.
