[~sergey.soldatov], I remember you mentioning something like this around CoprocessorConnections
(or was it ZK related?..)

> 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.
