John Vines commented on ACCUMULO-1708:
--------------------------------------
So it sounds like your ThreadGroup approach is a partial solution, but it's the
best we got so far. Do we see an overall fix including this approach? If so, I
think we should go ahead and see about making this change and document the
possibilities that can then occur for future tickets.

>
> A tserver experienced a OOME during minor compaction. This OOME was thrown
> because java could not create a native thread. Minor compactions only catch
> declared exceptions and RuntimeExceptions. This left the system in a state
> where the compaction was not running but the tserver thought it was. This
> cause"flush -w" to hang and prevented the tserver from reclaiming memory.
> For whatever reason the OOME handler that kills the process did not kick in
> (seems it only kicks in w/ OOME related to heap allocation).
