Meng Zhu commented on MESOS-9502:
---------------------------------
[~abudnik] pointed out that this is likely caused by MESOS-6632, which I can
confirm with the log.
When a container launch gets discarded halfway but after IOSB starts to
redirect to the container, the IOSB will be stuck there until agent fails over
and all fds are closed. I can confirm that stuck ISOB always comes back and
terminates after an agent failover.
> IOswitchboard cleanup could get stuck.
