> Key: MESOS-7748
> URL: https://issues.apache.org/jira/browse/MESOS-7748
> Project: Mesos
> Issue Type: Bug
> Reporter: Alexander Rukletsov
> Assignee: Alexander Rukletsov
> Priority: Critical
> Labels: mesosphere, reliability
>
> For each active subscriber, Mesos master / slave 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 / slave memory
> consumption, which might lead to an OOM event.
> Ideas to consider:
> * Restrict the number of subscribers for the streaming APIs
> * Check (ping) for inactive or "slow" subscribers
> * Disconnect the subscriber when there are too many queued events in memory
