This bug can be reproduced on puddle 1-2-RHSCL11-2014-05-20,but fixed on ose 2.0 and ose 2.1.

+++ This bug was initially created as a clone of Bug #1029679 +++

Description of problem:

[5282a2a5fa6006aabc000005]\> haproxy_ctld -u
/var/lib/openshift/5282a2a5fa6006aabc000005/haproxy/usr/bin/haproxy_ctld.rb:101:in `initialize': Connection refused - "/var/lib/openshift/5282a2a5fa6006aabc000005/haproxy/run/stats" (Errno::ECONNREFUSED)
        from /var/lib/openshift/5282a2a5fa6006aabc000005/haproxy/usr/bin/haproxy_ctld.rb:101:in `open'
        from /var/lib/openshift/5282a2a5fa6006aabc000005/haproxy/usr/bin/haproxy_ctld.rb:101:in `refresh'
        from /var/lib/openshift/5282a2a5fa6006aabc000005/haproxy/usr/bin/haproxy_ctld.rb:67:in `initialize'
        from /var/lib/openshift/5282a2a5fa6006aabc000005/haproxy/usr/bin/haproxy_ctld.rb:345:in `new'
        from /var/lib/openshift/5282a2a5fa6006aabc000005/haproxy/usr/bin/haproxy_ctld.rb:345:in `<main>'


It would be nice if an error message was returned indicating that the application had been stopped.

Checked on devenv_4056, issue has been fixed.

[php1s-bmengdev.dev.rhcloud.com 528d9863c8c92ebbbf00005e]\> haproxy_ctld -u
An error occurred; try again later: Could not connect to the application.  Check if the application is stopped.
[php1s-bmengdev.dev.rhcloud.com 528d9863c8c92ebbbf00005e]\> haproxy_ctld -d

I don't think this is serious enough to fix for 1.2.  Most customers are already running some version of 2.x.
