Raja, Could you run the StateChangeLogMerger tool and give it one topic-partition that has the above mentioned problem. This tool is documented here - https://cwiki.apache.org/confluence/display/KAFKA/Replication+tools#Replicationtools-7.StateChangeLogMergerTool .
Let me know if you run into any issues while using it.
