> This appeared in one of our clusters at Twitter.
> Looks like the slave webui process (which is a fork of mesos-slave) is not properly shutting down.
> Couple of things that need to happen to fix this
> 1) Set FD_CLOEXEC on any opened pipes, because we see a bunch of shared file descriptors between slave webui and the executors.
> 2) Explicitly call executor shutdown, to give it a chance to clean up
