Flink Jira Bot updated FLINK-21161:
-----------------------------------

I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help the community manage its development. I see this issues has been marked as Major but is unassigned and neither itself nor its Sub-Tasks have been updated for 30 days. I have gone ahead and added a "stale-major" to the issue". If this ticket is a Major, please either assign yourself or give an update. Afterwards, please remove the label or in 7 days the issue will be deprioritized.

> The datadog reporter sends reports to datagod via asynchronous calls made with okhttp.
> okhttp buffers requests if they cannot be submitted; if any connection issues it might be possible for enough data to be buffered to cause an OOM.
> By default the number of concurrent requests is set to 64. We should try to reproduce the problem, and check whether setting this to a lower value would solve it.
