             Summary: cgroups/net_cls isolator causing agent recovery issues
                 Key: MESOS-5879
                 URL: https://issues.apache.org/jira/browse/MESOS-5879
             Project: Mesos
          Issue Type: Bug
          Components: cgroups, isolation, slave
            Reporter: Silas Snider


We run with 'cgroups/net_cls' in our isolator list, and when we restart any agent process in a cluster running an experimental custom isolator as well, the agents are unable to recover from checkpoint, because net_cls reports that unknown orphan containers have duplicate net_cls handles.

While this is a problem that needs to be solved (probably by fixing our custom isolator), it's also a problem that the net_cls isolator fails recovery just for duplicate handles in cgroups that it is literally about to unconditionally destroy during recovery. Can this be fixed?
