>
> 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).
