Local Aruba Controller running very slow, keeps dropping connection to APs

    We have a two site configuration, master controller at main location and local at secondary. The sites are 50 miles apart but have a dedicated network connection that they utilize to sync connection. The issue is that the local controller runs very slow, even when accessed onsite and often the APs that are connected to the local controller lose connection. The only way to re-establish connection is to reboot the controller. Lately, I have had to do this weekly if not more. Is anyone else having this issue? Both controllers are on version 6.1.3.2.

    Can you do the following commands :

     

    (controller) #show  cpuload current

     

    (controller) #show  cpuload 

     

    And also pick one of the APs that keeps rebooting and run this one show ap debug system ap-name <apname>

    With those outputs for your knowledge why fabian is aksing you that

     

    On the cpu utilization you should consider the CPU to be highly utilized at 70% (begin monitoring regularly) and considered critical at 100% (being investigating) over a 5-minute period

     

    On the memory you should consider that the memory is moderately utilized at 30 Mb free (begin monitoring
    regularly) and highly utilized at 15 Mb free (being investigating) over a 5-minute period.

     

    For the last one do show memory

    Thank you both for replying. Thus far, the reboot has worked. I will use your commands to monitor the controller to see if I can narrow down what specific task or event is causing the slowdowns.
