[jboss-jira] [JBoss JIRA] Deleted: (JGRP-170) upTbl should be cleared in _upViewChange()

upTbl should be cleared in _upViewChange() ------------------------------------------ Key: JGRP-170 URL: https://issues.jboss.org/browse/JGRP-170 Project: JGroups Issue Type: Bug Reporter: Bela Ban Assignee: Bela Ban upTbl should be cleared in _upViewChange(). Say there are three nodes A,B,C. Suppose there are 10 outstanding TOTAL sequences say 1-10 (1-5 from A and 6-10 from B). Say seq#1 is missing so we have 2-10 in every upTbl. Now assume the view changes and A and B replayBcast (). This time A gets 6-10 and B gets 1-5. A lot can go wrong now, say if A's sequences reach in reverse order. We have duplicate transmissions from A. Its also possible that B's transmission is totally lost. I haven't verified all possible scenarios here, but I think the above two are quite possible.
