Linux Agent - Error - Replication Driver Missing

{code}An exception occurred during the request. Replication driver missing; Unable to open driver at '/dev/hcp'; No such device or address.{code}

This error indicates that the CDP Agent kernel driver is not installed for the running kernel on the agent's Operating System. This can happen when the agent OS is rebooted into a new kernel after running an upgrade (usually Apt or Yum). Or this can occur if you have not installed a CDP Agent kernel driver after the initial install of the CDP Agent.
