Alexander Behm resolved IMPALA-4691.
------------------------------------
    Resolution: Cannot Reproduce

There is not enough information for us to make progress on this. Feel free to re-open if you
can provide a core or a stack trace. Many known issues could have caused this behavior, so
I'd recommend upgrading as a first step.
