@clebertsuconic It appears the original issue was introduced when you
changed the ReplicationManager to skip the executor and send in the same
thread. I am trying to understand why this was required. From a quick read of
the code, I assume that when sending a large file there's potential for the
whole file to get scheduled on the ThreadPoolExecutor Queue, with potential to
cause an OOM? Is this assumption correct?
