>             Project: Apache Drill
>          Issue Type: Bug
>          Components: Web Server
>    Affects Versions: 1.13.0
>            Reporter: Kunal Khatua
>            Assignee: Kunal Khatua
>            Priority: Major
>              Labels: ready-to-commit
>             Fix For: 1.14.0
> 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.
