MSM765 High utilization, proc regng use 90%

[Johnny Persson]

Hi
We have a MSM765 that is very slow when we access it thru the WEB-GUI, it also drops AP´s and then after some time (a few hours) finds them again.
When running top we can see that the process regng is using round 90%

What is wrong ?

Best Regards
Johnny Persson

Which software version do you have?

What type of VSC's do you have setup?

How many APs and what type?

Attach the log also if you can.

I've had a similar issue with a msm 760 and 730. They are both running the same 5.5.something firmware. Cpu usage pegs at 90 or 100% and the connection to outside radius server fails. Started after I upgrade to the first 5.5 release.

have disabled the LLDP agents under Network > discovery protocols > lld agents and the result was amazing

Same problem, HP suggest to upgrade to 5.7.0.3, but the problem still remains.

Disabled LLDP both on controller and APs: good results!

Disabled mobility manager also: CPU load goes lower again.

We have 5 teamed controllers, 640 AP.

From 6.5 load to 1.2 now.

Thanks aesmat for the suggestion!
