Silas Snider commented on MESOS-5879:
-------------------------------------

Have you made much progress on this? I'm asking because I got permission to contribute back the fix we're using right now, which just ignores child cgroups in the net_cls isolator.

> 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?
