Kafka Streams version - 2.0.0 Hi, in our streaming instance we are observing a steady growth in the off-heap memory (out of 2gb allocated memory 1.3 is reserved for heap memory and the ~700mb memory is utilised over a time of ~6hrs and the process is OOM killed eventually).
we are using only the inMemoryKeyValueStore and not doing any persistence. as suggested the iterators are closed at the places it is used(using it in only once). Some forums were relating such issues with rocksdb but we are not specifying rocksdb in the config explicitly though. I was not sure whether it is used as a default in memory store by kafka streams.
