> Assignee: Saksham Gangwar
> Priority: Major
> Fix For: 4.16.0
>
>
> In https://issues.apache.org/jira/browse/PHOENIX-5872
> We started maintaining parent-child relationships between phoenix connections to close those connections. But after closing those child connections we should be removing them from the Queue which is being maintained for the same.

> If not removed from the queue, and if the parent connection is being reused: we are observing the OOM issue on the container side during the mapper run.
