----------------------------------
The above stack trace is not helpful for tracing the root cause. If you can get
the JobMaster log, then it is easy to find the first failure reason which
causes the above buffer pool destroyed.
> buffer pool is destroyed

> Key: FLINK-14525
> URL: https://issues.apache.org/jira/browse/FLINK-14525
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Network
> Affects Versions: 1.7.2
> Reporter: Saqib
> Priority: Blocker
>
> Have a flink app running in standalone mode. The app runs ok in our non-prod
> env. However on our prod server it throws this exception:
> Buffer pool is destroyed.
>
> This error is being thrown as a RuntimeException on the collect call, on the
> flatmap function. The flatmap is just collecting a Tuple<String, Document>,
> the Document is a XML Document object.
>
> As mentioned the non prod env (and we have multiple, DEV,QA,UAT) this is not
> happening. The UAT box is spec-ed exactly as our Prod host with 4CPU. The
> java version is the same too.
>
> Not sure how to proceed.
>
> Thanks
