Hello all, Recently I got incident with kafka cluster, I found OutOfMemoryError in kafka server log
> WARN [ReplicaFetcherThread-0-2], Error in fetch Name: FetchRequest; > Version: 0; CorrelationId: 7041716; ClientId: ReplicaFetcherThread-0-2; > ReplicaId: 0; MaxWait: 500 ms; MinBytes: 1 bytes; RequestInfo:[. . . . .]. > Possible cause: java.lang.OutOfMemoryError: Java heap space > (kafka.server.ReplicaFetcherThread) And at the same time there are socket timeout exceptions in kafka consumer. Is there any hypothesis about what might be wrong? Here is the cluster spec : 3 hosts, @ with memory 16 G partitions : ~200 replication factor : 3 rate in : 300 K/s rate out : 800 K/s Thank you, -- Muqtafi Akhmad Software Engineer Traveloka
