MSM765 High utilization, proc regng use 90%

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

Re: MSM765 High utilization, proc regng use 90%

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.

Re: MSM765 High utilization, proc regng use 90%

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.

Re: MSM765 High utilization, proc regng use 90%

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!
