    Description

      • We have {A,B,C,D}
        - D is slow, and gets excluded, so A,B,C see themselves as view, but D has view {A,B,C,D}
      • When we want to merge {A,B,C}

        and

        {A,B,C,D}

        , the latter subgroup has existing seqnos for A, B and C in UNICAST, whereas the former doesn't

      • Say, D has seqnos A:25, B:7 and C:3, and sends a unicast message 26 to A, but A expects #1, then we have an issue

      We cannot trash UNICAST connection tables because of JGRP-659
