> In default jgroups-tcp.xml [1]:
> <MFC max_credits="200k" min_threshold="0.20"/>
> <FRAG2 frag_size="60000"/>
> According to JGRP-1659 [2]:
> * Either set FRAG2.frag_size to be less than MFC.min_threshold * MFC.max_credits (=40k), e.g. to 20k, or
> * Increase max_credits or min_threshold, such that their product is greater than FRAG2.frag_size
> Recommend updating default jgroups-tcp.xml accordingly.
