Hi Rajini, Thanks for reporting this issue. Could you please file a JIRA for this.
I basically agree that this is probably a synchronization issue, which might not be caught correctly right now. Could you also try the SCR 1.0.1-SNAPSHOT ? This contains some more logging, which could help resolve the issue.
