> Potential memory leaks in the `volume/sandbox_path` isolator

> Key: MESOS-8651
> URL: https://issues.apache.org/jira/browse/MESOS-8651
> Project: Mesos
> Issue Type: Bug
> Components: containerization
> Reporter: Jason Lai

> Fix For: 1.4.2, 1.6.0, 1.5.1, 1.3.3

>
> The {{sandboxes}} hashmap object of
> {{mesos::internal::slave::VolumeSandboxPathIsolatorProcess}} bears the risk
> of potential memory leak.
> It [adds the sandbox path upon each container
> launch|https://github.com/apache/mesos/blob/1.5.x/src/slave/containerizer/mesos/isolators/volume/sandbox_path.cpp#L119-L122]
> and does not remove the sandbox path after cleaning up the container. As the
> life cycle of an isolator is attached to that of {{MesosContainerizer}}, this
> means that more and more sandbox paths will get added to the {{sandboxes}}
> hashmap object, as Mesos containers keep being launched and will likely blow
> up Mesos agent eventually.
