> The AM does not have any flow control to limit the incoming rate of events from tasks. If the AM is unable to keep pace with the rate of incoming events for a sufficient period of time then it will eventually exhaust the heap and crash. MAPREDUCE-5043 addressed a major bottleneck for event processing, but the AM could still get behind if it's starved for CPU and/or handling a very large job with tens of thousands of active tasks.
