That sounds about right.
So, I'll try to play around with private static final int MAX_BUFFERED_QUERIES and update you guys.
Thanks a bunch.

Almost certainly. The thing to look at is setting the network buffer sizes to use to large values to avoid the

areunfortunately not documented, but were introduced in this commit:
