5508 Controller - "Locked Up"

Hi all,

Bit of a strange one. Earlier today my WLC locked up completely for management traffic. I was unable to https, ssh or console to the controller until I rebooted it. Wireless access seemed to be unaffected by the issue which is even more puzzling.

The controller is lightly used at the moment:

4 wireless networks (approx 1500 users)
4 DHCP scopes (approx 1500 addresses across 4 subnets).

It looks like a possible temp issue (internal temp is currently +42C and falling) but I would be interested to know if anyone has come across the same issue?

Software Version 7.5.102.0.

Thanks.

Upgrade your controller to 7

Upgrade your controller to 7.6.120.X if possible.  

 

It sounds like the Management IP Address has some ARP issues.  Did you try to clear the ARP table?
