> In a heap dump it could be seen that a client request retries on the same follower multiple times and every time the request is rejected with a NotLeaderException. In case of Ozone it is a WriteChunk request which leads to garbage collection of 16MB for every request. In the heap dump a client request retries multiple times leading to garbage collection of ~100MB.
