> http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Source-Operators-Stuck-in-the-requestBufferBuilderBlocking-tt42530.html
> We received two similar reports in the past, but the users didn't follow up,
> so it was not as easy to diagnose as this time where the initial report
> already contains many relevant data points.
> Beside a buffer leak, there could also be an issue with priority notification.
