             Summary: GMS: low leave_timeout may cause incorrect view installation
                 Key: JGRP-1509
                 URL: https://issues.jboss.org/browse/JGRP-1509
             Project: JGroups
          Issue Type: Bug
            Reporter: Bela Ban
            Assignee: Bela Ban
             Fix For: 3.0.15, 3.2


- {A}
- B joins, then C, the view is A2={A,B,C}
- *No* messages are sent
- GMS.leave_timeout=100
- NAKACK2.xmit_interval=1000
- A leaves gracefully (JChannel.disconnect())
- A multicasts B3={B,C}, the seqno is #3
- B discarded A#2 (view {A,B,C}), as it was not yet server
- B now asks A for retransmission of #2 before it can deliver #3 (the new view)
(- The retransmission kicks in ca. every 1 sec)
- However, A is gone, so C will loop asking A to retransmit #3 and will therefore never install view B2 !
