Avinash Sridharan commented on MESOS-5879:
------------------------------------------
A bit confused. I thought you mentioned that the custom isolator and no other
component in your system touches the handle? So not sure how we are ruling out
the Agent? Unless we are not completely sure the components in the system are
"not" touching the `net_cls` cgroup.
> 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
> Assignee: Avinash Sridharan
>
> 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?
