RFC 5176

"Session Context Not Removable" is a fatal error sent in response
to a Disconnect-Request if the NAS was able to locate the session
context, but could not remove it for some reason.  It MUST NOT be
sent within a CoA-ACK, CoA-NAK, or Disconnect-ACK, only within a
Disconnect-NAK.


ensure that ALL the things you are sending to the device are present
on the device.... ie X-Ascend-Session-Svr-Key ?
