WLC 9800 CPU Utilize Issue - Page 3

bakaholic39 · ‎07-11-2023

Hi,

I have a WLC 9800 on Firmware OS : 17.9.3
19 APs and 100 Clients

Everything looks normal, but there are reports that the CPU utilization rate is too high. The problem is only 7th core. Has anyone encountered the same problem as me. What should I do to solve it?

Thank you!

I think it's fair to say that the CPU use (due to QFP emulation using CPU core) is not the same as an obvious process memory leak @Leo Laohoo - one is a cosmetic issue due to the software design and the other is a severe bug due to memory leak.
