[ https://issues.jboss.org/browse/JGRP-1830?page=com.atlassian.jira.plugin.... ] 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 -- This message was sent by Atlassian JIRA (v6.4.11#64026)
