Highest seqno is not resent nor recorded on receivers ----------------------------------------------------- Key: JGRP-2167 URL: https://issues.jboss.org/browse/JGRP-2167 Project: JGroups Issue Type: Bug Affects Versions: 4.0.1 Reporter: Radim Vansa Assignee: Bela Ban Fix For: 4.0.3 I am investigating an issue in a stress test which leads me to a situation where in a TCP-based configuration a {{GMS[VIEW]}} is broadcast to all nodes, but it is not received by some of them. Soon after that there's a {{NAKACK2.HIGHEST_SEQNO}} that causes the node that is missing the last seqno to resend it, but the retransmit is not received either. There are no further retries, and generally no NAKACK2 activity until about 30 seconds later (when another node leaves after some timeout in the test). The receiver does not keep asking for retransmissions until it gets them, but it seems that {{NAKACK2.handleHighestSeqno}} doesn't update {{Table.hr}} (not sure if having highest received set to non-received msg would be legal, though). The sender uses default value {{NAKACK2.resend_last_seqno_max_times=1}}, and as there are no further mcast messages, the highest sent seqno does not change on sender.
