    [ https://issues.jboss.org/browse/JGRP-1830?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13161679#comment-13161679 ] 

Bela Ban commented on JGRP-1830:
--------------------------------

Also handle the case where a crash leads to a gap, e.g. A gets 3, B gets 4 and C gets 5, but B crashes before sending message #4.
Everyone receives 3(2) -> 5(4), but 4 is missing.
SOLUTION:
* The coord needs to keep track of seqnos dished out to members (e.g. 4 to B) and send a message to skip the missing ones on a crash of B.
* This state needs to be kept until everyone has received B#4. How do we know that?
* What happens with this state when the coord itself crashes?
** The reconciliation phase described above needs to be able to reconstruct this state
