Comment 1 Daniel Walsh 2015-03-16 19:26:08 UTC
This will require a new build of docker-1.5.0

Comment 2 Lokesh Mandvekar 2015-03-19 06:31:54 UTC
with docker-1.5.0-20.el7, Fds seem to be in the range 13-15 and Goroutines are in 19-21 on my system. Don't seem to increase beyond that.

Comment 4 Luwen Su 2015-03-25 07:44:43 UTC
docker-1.5.0-26.el7.x86_64, both fd and Goroutine are stable.(no longer exceed 26 and 37 on my machine)
#terminal 1
# while true; do docker run -it --rm rhel7 /bin/true ; done
