Last week we upgraded the WiSM controllers from version 4.2.207 to 6.0.182 Since then, one of the controllers' CPU stays at 95%. Yesterday I reloaded the controller and after a couple of hours it went back to using 95% CPU. On this state, it is not possible to logon to the controllers either from the console, session from the Cat6509 or SSH. The controller responds to queries and changes from WCS and seems to be servicing clients properly. Is there any other way to find out what is consuming the CPU? I have looked on WCS but being unable to find anything. Perhaps an SNMP MIB that I can query.
Thanks for any information
