Comment 1 for bug 1728278

Hi All,

As I said earlier both openstack and contrail-api services failed due to the presence of lower version of
oslo.confg package in node(10.102.28.138).

Fixed by
1. pip uninstall oslo.config
2. service supervisor-config restart
3. service supervisor-openstack restart

You may need to find out how lower version of oslo.config was installed in first config node(10.102.28.138)
