The CDM probe is not starting and has a "Max Restarts" error in the cdm log file. The CDM probe use to work on these servers.
If you set the controller to log level 5 and restart the robot you will see the following line
Controller: Can not start cdm, start after probe not enabled (cluster)
If the cluster probe is installed on the same machine as CDM, the cluster probe must be activated first.
Simply activate the cluster probe.
If you no longer need the cluster probe, uninstall it through the Infrastructure Manager or Admin Console GUI.
