Subject Re: Registry issue when persisting topology
Date Mon, 14 Sep 2015 17:18:41 GMT
Hi Udara,

Were you able to resolve this? Looks like Stratos integration tests are
failing due to same issue. It seems Carbon registry transactions are
failing when mock iaas component is trying to persist data.

Thanks.
