Default jgroups-tcp.xml configuration could result in JGroups lock

    Details

      Description

      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.
