Rajeshbabu Chintaguntla commented on PHOENIX-4685:
--------------------------------------------------

[~jamestaylor] Yes exactly that's what I have observed to in StoreNullsIt test output which
has hanging.
+1 on the addendum3. It should fix the failures.

> Currently trying to write data to indexed table failing with OOME where unable to create
native threads. But it's working fine with 4.7.x branches. Found many threads created for
meta lookup and shared threads and no space to create threads. This is happening even with
short circuit writes enabled.
