Machine stuck running DinD on CentOS 6.5

[kashyap-parikh]

I am trying to run DinD on CentOS 6.5 VM + Docker Version 1.3.2 running in virtualbox on a mac.
Using /fedora example I was able to build dind image. The only change I had to make was replacing CGROUP=/sys/fs/cgroup with CGROUP=/cgroup in wrapdocker.

When I try to start dind it freezes the host VM. Just before the freeze I see that mkfs.ext4 is using 100% cpu.

To reproduce:

vagrant box centos65 https://github.com/2creatives/vagrant-centos/releases/download/v6.5.3/centos65-x86_64-20140116.box
vagrant box init centos65
vagrant up
vagrant ssh
$ git clone git@github.com:jpetazzo/dind.git
$ cd dind/fedora
Change Dockerfile "FROM centos:6"
Change wrapdocker "CGROUP=/cgroup"
$ sudo ./build.sh
$ docker run --privileged -t -i -e DOCKER_DAEMON_ARGS="-D" dind

Here's the console log with last few lines before VM freezes. The only way to recover is shutdown and start.

can you try with the latest version of docker also we need the output of docker version, docker info, uname -a

[kashyap-parikh]

Below is uname and screenshot. Latest docker version for CentOS 6.5 is 1.4.1 and it has another issue #9856 that forced me to revert to 1.3.2.

[vagrant@vagrant-centos65 ~]$ uname -a
Linux vagrant-centos65.vagrantup.com 2.6.32-431.3.1.el6.x86_64 #1 SMP Fri Jan 3 21:39:27 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

ping @vbatts

thanks for the info @kashyap-parikh

@kashyap-parikh Please run yum update to update your CentOS system and reboot it afterwards.

[unclejack]

I'm going to close this issue now because it's been reported against Docker 1.3.2 and kernel 2.6.32-431. There are newer kernels available for CentOS 6.x and they can be easily installed via yum update and they can be used by running reboot to start using them.

If you can reproduce this with a fully updated system, please comment on this issue.
