> Key: MESOS-4535
> URL: https://issues.apache.org/jira/browse/MESOS-4535
> Project: Mesos
> Issue Type: Bug
> Components: modules
> Reporter: Joseph Wu
> Assignee: Joseph Wu
> Priority: Blocker
> Labels: logging, mesosphere
>
> One of the patches for [MESOS-4136] introduced the {{FDType::OWNED}} enum for
> {{Subprocess::IO::FD}}.
> The way the logrotate module uses this is slightly incorrect:
> # The module starts a subprocess with an output {{Subprocess::PIPE()}}.
> # That pipe's FD is passed into another subprocess via
> {{Subprocess::IO::FD(pipe, IO::OWNED)}}.
> # When the second subprocess starts, the pipe's FD is closed in the parent.
> # When the first subprocess terminates, the existing code will try to close
> the pipe again. This effectively closes a random FD.
