Anand Mazumdar commented on MESOS-5914:
---------------------------------------
Thanks for reporting this. We recently fixed this by introducing an environment
variable to control the amount of libprocess threads as part of MESOS-4353. The
fix should be available in 1.0. I am resolving this for now. Feel free to
reopen in case you have any further queries.

> Environment: CentOS7
> Kernel 4.6.2-1.el7.elrepo.x86_64
> Docker 1.11-2
> Reporter: Lei Xu
> Priority: Minor

> I found mesos-docker-executor initialize many threads when running a docker
