> Drillbit hangs/crashes with OOME Java Heap Space for a large query through
> WebUI
> --------------------------------------------------------------------------------
>
> Key: DRILL-6477
> URL: https://issues.apache.org/jira/browse/DRILL-6477
> Project: Apache Drill
> Issue Type: Bug
> Components: Web Server
> Affects Versions: 1.13.0
> Reporter: Kunal Khatua
> Assignee: Kunal Khatua
> Priority: Major
> Fix For: 1.14.0
>
> Original Estimate: 48h
> Remaining Estimate: 48h
>
> For queries submitted through the WebUI and retrieving a large resultset, the
> Drillbit often hangs or crashes due to the (foreman) Drillbit running out of
> Heap memory.
> This is because the Web client translates the resultset into a massive object
> in the heap-space and tries to send that back to the browser. This results in
> the VM thread actively trying to perform GC if the memory is not sufficient.
