Routing Engine (RE) is unresponsive and displaying the above messages

As workaround step, we recommend proceeding with reseat of the affected Routing Engine (RE).

However, if the reseat does not help to clear the messages and resolve the issue, then we will need to replace the affected RE.
Note: if still required, please contact Juniper Networks for further assistance and investigation.
