Bug 872084

Description of problem:
Create a scalable application,and embed db cartrdige,but will get this information:Connection to server timed out. It is possible the operation finished without being able to report success. Use 'rhc domain show' or 'rhc app status' to check the status of your applications.
And use 'rhc domain show',sometimes will get error,like:/usr/lib/ruby/gems/1.8/gems/rhc-1.0.3/lib/rhc/rest/cartridge.rb:68:in `connection_info': undefined method `rstrip' for nil:NilClass (NoMethodError)

Sometimes,I can not create a scalable applicaion,will get :Node execution failure (invalid exit code from node).  If the problem persists please contact Red Hat support.

Version-Release number of selected component (if applicable):
INT(devenv_2417)

How reproducible:
Sometimes

Steps to Reproduce:
1.create a scalable application
rhc app create -a $name -t $type -s
2.embed db cartridge
rhc cartridge add $db -a $appname
3.rhc domain show


Actual results:
