We're seeing a situation in one of our clusters where a message will occasionally be duplicated on an incorrect topic. No identifiable issues spotted in either the client application or kafka logs.
Has anyone else see this? Seems like something that would raise concern. Any recommendations for enhanced logging? Client: 0.8.2.1 java producer with ISR acks Cluster: 0.8.2.2 w/Scala 2.10.1, 3 replicas per topic
