    Description

      When UNICAST3 or NAKACK2 send XMIT_REQs, they serializes SeqnoList as payload without any limits upon its size. If there are too many missing messages, the XMIT_REQ grows over TP.max_bundle_size and cannot be sent at all.

      JGRP000029: edg-perf03-10774: failed sending message to edg-perf01-63702 (64072 bytes): java.lang.Exception: message size (64072) is greater than max bundling size (64000). Set the fragmentation/bundle size in FRAG and TP correctly, headers: UNICAST3: XMIT_REQ, seqno=0, UDP: [channel_name=default]
      

      It's also undesirable to resend thousands of messages, as the receiver likely cannot process them all at once and only few of them will be actually processed. Therefore only X oldest ones (in order to cleanup the tables) should be resent.
