------------------------------------------
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
