When connecting to the cluster manager, the agent has passed an incorrect value for the security level used to connect to the cluster manager. The AgentSecurity value in the XML is derived from the
-cmsecurity option when starting the agent. Valid values are:
* 0 for "none"
* 1 for "relaxed"
* 2 for "strict"
Something has gone wrong when the agent connected to the cluster manager and the value for AgentSecurity in the XML is not a valid value.
