Problem with retransmission: message not found
----------------------------------------------

                 Key: JGRP-455
                 URL: http://jira.jboss.com/jira/browse/JGRP-455
             Project: JGroups
          Issue Type: Bug
    Affects Versions: 2.4.1 SP1
            Reporter: Bela Ban
         Assigned To: Bela Ban
             Fix For: 2.5


Sometimes a sender cannot find a message with a seqno as requested by a receiver. The seqno requested (47176) was already purged, sent_msgs:  [48059 - 48090] (32)

This could be either an issue in STABLE, which prematurely purges messages although not all members agreed on the highest seqnos seen, or NAKACK, which might incorrectly 'change' seqnos. Very hard to reproduce !

Trace:
