> Project: Apache Drill
> Issue Type: Bug
> Components: Server
> Affects Versions: 1.10.0
> Environment: - ubuntu 14.04
> - r3.8xl (32 CPU/240GB Mem)
> - openjdk version "1.8.0_111"
> - drill 1.10.0 with 8656c83b00f8ab09fb6817e4e9943b2211772541 cherry-picked

> Per the mailing list discussion and Rahul's and Paul's suggestion I'm filing this Jira issue. Drill seems to be running out of memory when doing an External Sort. Per Zelaine's suggestion I enabled sort.external.disable_managed in drill-override.conf and in the sqlline session. This caused the query to run for longer but it still would fail with the same message.
> Per Paul's suggestion, I enabled debug logging for the org.apache.drill.exec.physical.impl.xsort.managed package and re-ran the query.
> Here's the initial DEBUG line for ExternalSortBatch for our query:

> And here's the last DEBUG line before the stack trace:
