> I tried looping this test for a while to flush out a different issue and
> discovered a memory leak:
> {noformat}
> while impala-py.test tests/query_test/test_spilling.py -k naaj -n4 --verbose;
> do date; done
> {noformat}
> Eventually the test fails with "Memory Limit Exceeded" and there is a huge
> amount of untracked memory reported on /memz.
> I tried running the heap growth profiler and the only suspicious thing I saw
> was CRYPTO_malloc, similar to IMPALA-6792. My current hypothesis is that it's
> something related to disk spill encryption and we haven't noticed it before
> because we had disk spill encryption off.
> If I disable encryption "start-impala-cluster.py
> --impalad_args=--disk_spill_encryption=false" then I don't see the leak.
