@caishize too many threads will cause high sys cpu usage. much worse
situation, the node will be halt.
I see there are 31 workers in your machine, what's the total thread
number? reducing the number of threads should bring a improvement.

>
> In secure multitenant storm, topology workers are launched with permission of
> the user that submitted the topology. This causes a problem with cgroups
> since workers are launched with permissions of the topology user which does
> not have permissions to modify cgroups storm is using
> Also, the clean up code is not trying to clean up cgroups of killed workers
> if the initial attempt failed
