--------------------------------
Summary: 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
Assignee: Jason Lai
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.
