             Summary: Streaming API subscribers can lead to Mesos master OOM event.
                 Key: MESOS-7748
                 URL: https://issues.apache.org/jira/browse/MESOS-7748
             Project: Mesos
          Issue Type: Bug
            Reporter: Alexander Rukletsov
            Assignee: Alexander Rukletsov


For each active subscriber, Mesos master maintains an event queue, which grows over time if the subscriber does not read fast enough. As the number of such "slow" subscribers grows, so does Mesos master memory consumption, which might lead to an OOM event.

Ideas to consider:
* Restrict the number of subscribers for the streaming API
* Check (ping) for inactive or "slow" subscribers
* Disconnect the subscriber when there are too many queued events in memory
