Max CPU usage MCM760

jhooverpfcu — Wed, 26 Dec 2018 15:54:37 GMT

I am currently investigating 100% CPU usage on our MCM760 when looking at top I see 3 processes consuming all the CPU and they are the following

16591 root R 8068 440 73.0 0.3 nbstationsd
15398 root R 53M 440 65.2 2.6 iprulesmgr
14463 root R 10004 440 50.5 0.4 gandalf

I am new to HP networking equipment so I am unfamiliar with these processes and do not know what exactly they are for. I would appreciate any help I could get.

Current software version is 6.6.0.0 -22530

Hi,

How many controllers?

How many accesspoints?

How many users?

Authentication - local or radius?

When was the controller last reboot?

I appreciate the reply, a reboot did fix the issue after I noticed the uptime of the devices were over 800 days I assumed that was likely the cause of the high CPU usage.

How many controllers? - 2

How many accesspoints? - 40

How many users? - 200+

Authentication - local or radius? - local

When was the controller last reboot? 800+

Ok Great.

I have never been able to run stable over 150 days or so.

The MSM760's always becomes a little unstable. Nothing you can put a finger on but it always "works" better if I keep the uptime low.

A quick restart during some holiday keeps it all fresh ;-D

Good to know and I will keep that in mind. I am still getting used to this whole HP environment.
