Whenever a user switches from an HTTP to HTTPS location, the server produces many Secure Sockets Layer (SSL) exceptions and potentially locks up.
This issue is documented in Cisco bug ID CSCsc69262.
The Cisco location appliance that is currently integrated into the wireless system stops responding correctly to the getserverinfo command, and the Server Events log in the Wireless Control System (WCS) server shows THROW events. There are many events of messages from WCS under Location Server > Server Events.
The location appliance enhances the high-accuracy built-in WCS location capabilities by computing, collecting,and storing historical location data, which can be displayed in WCS. In this role, the location appliance acts as a server to a WCS server by collecting, storing, and passing on data from its associated controllers.
This issue is first found in version 2.0(31) and is first fixed in these versions:
As a workaround, disable HTTPS access between the location appliance and the WCS by unchecking the box.
