Hi Mayur, thanks for letting us know! While the scenario leading to this error messages seems to be quite an edge-case, the handling of it inside Graylog wasn't 100% correct.
I've created a bug report (and fix) for this issue at https://github.com/Graylog2/graylog2-server/pull/2833 and it will be solved in Graylog 2.2.0.
