----------------------------------

             Summary: `network/ports` isolator kills legitimate tasks on recovery.
                 Key: MESOS-8440
                 URL: https://issues.apache.org/jira/browse/MESOS-8440
             Project: Mesos
          Issue Type: Bug
          Components: containerization
    Affects Versions: 1.5.0
            Reporter: James Peach
            Assignee: James Peach


At recovery time, the containerizer sends all the resources *except* the ports. This means that the ports check will race against the subsequent resources update. The root cause of this is that only the executor resources are provided at recovery time, whereas at update time the isolator gets the whole container resources as calculated by {{Executor::allocatedResources()}}.
