Description of problem:

We are trying to build docker image. It was working fine on Docker version
1.2.0, build fa7b24f/1.2.0. But up gradation to latest 1.4 it's started
hangs.We were unable to build images anymore.

Version-Release number of selected component (if applicable):

$ sudo docker -v
Docker version 1.4.1, build 5bc2ff8/1.4.1

$ sudo docker info
Containers: 2
Images: 110
Storage Driver: devicemapper
 Pool Name: docker-8:17-2228225-pool
 Pool Blocksize: 65.54 kB
 Data file: /var/lib/docker/devicemapper/devicemapper/data
 Metadata file: /var/lib/docker/devicemapper/devicemapper/metadata
 Data Space Used: 12.64 GB
 Data Space Total: 107.4 GB
 Metadata Space Used: 15.24 MB
 Metadata Space Total: 2.147 GB
 Library Version: 1.02.89-RHEL6 (2014-09-01)
Execution Driver: native-0.2
Kernel Version: 2.6.32-431.29.2.el6.x86_64
Operating System: <unknown>
CPUs: 1
Total Memory: 1.833 GiB

How reproducible:

Install docker using following steps

1) Run wget
http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm or
wget "http://epel.mirror.srv.co.ge/6/i386/epel-release-6-8.noarch.rpm"
2) Run sudo rpm -Uvh epel-release-6*.rpm
3) Run sudo yum -y install docker-io
4) Run sudo service docker start
5) cd /etc/yum.repos.d 
6) sudo wget public-yum.oracle.com/public-yum-ol6.repo
7) sudo wget public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 -O
/etc/pki/rpm-gpg/RPM-GPG-KEY-oracle 
8) sudo yum update device-mapper
9) sudo service docker restart

Any Dockerfile can be used to reproduce issue.

FROM ubuntu

# Install vnc, xvfb in order to create a 'fake' display and firefox
RUN ls
EXPOSE 5900
CMD    ["uname"]

Steps to Reproduce:
1. Install docker-io as mentioned above
2. use above dockerfile or any then run docker build -t "sample" --rm=true .
3. 90% it hangs node, session will be lost.

Actual results:

hangs node, session will be lost.

Expected results:

Should build images

Additional info:

Tried sudo yum update as mentioned in the below site. But still problem remains
same

sorry but I gotta ask, what's the additional oracle repo for? Is this to update
device-mapper that's otherwise not present in rhel6/el6 ?

Could you check if docker-io-1.5.0-1 takes care of this? Certainly works for me
as did 1.4.1-3. 1.5.0-1 is in epel6-testing. If not, please read on..

'any Dockerfile' sounds too vague a term. Could you let me know if your
Dockerfile above is complete? The comment up there sounds like there's an
'apt-get install...' step needed.

Going by the above comment, here's the Dockerfile I assume you'd want to use
(correct me if I'm wrong):
---Dockerfile---
FROM ubuntu
RUN apt-get update
RUN apt-get -y install firefox xvfb vnc4server
RUN ls
EXPOSE 5900
CMD ["uname"]
---Dockerfile---

and docker build with this Dockerfile gives me:
(uses cache to keep output short)
$ sudo docker build .
