Stephen Mallette closed TINKERPOP-2552.
---------------------------------------
Resolution: Cannot Reproduce
I've not seen this problem in a while. Unclear how to recreate it, especially
now. Closing until it rears up again.

> Not sure if it's related but intermittent failures in Travis have usually be
> caused by the tests executing in a low resource environment. Tests that have
> timers, rely on multiple threads, etc. tend to show their problems in Travis.
> HadoopMarc had the nice idea to often reliably recreate these errors in
> Docker by setting {{cpus=0.9}} - again, unsure if this is the issue, but it
> would be nice if we could get to the bottom of this for travis sake but also
> because it might be a subtle bug that folks are running into.
