[ https://issues.jboss.org/browse/JGRP-2167?page=com.atlassian.jira.plugin.... ] Bela Ban edited comment on JGRP-2167 at 5/11/17 4:58 AM: --------------------------------------------------------- OK, I added unit test {{LastMessageDroppedTest.testLastMessageAndLastSeqnoDropped()}} with {{STABLE.desired_avg_gossip_time}} set to 3000. This passes fine. The test drops msg #3 out of 3 messages, and also drops the subsequent LAST_SEQNO (HIGHEST_SEQNO) message. However, STABLE kicks in and fixes this. The time range is {{\[0 .. avg_desired_gossip_time*2\]}}, so in the above test the max is ~6 seconds. If you want, we can add another fixed time interval {{stable_interval}} which would send at fixed time (not random times within a range), to make this more predictable. This would (if set) override {{avg_desired_gossip_time}}. Note that STABLE messages are sent _unreliably_, so if a STABLE message is dropped, we have to wait for the next round to get stability. was (Author: belaban): OK, I added unit test {{LastMessageDroppedTest.testLastMessageAndLastSeqnoDropped()}} with {{STABLE.desired_avg_gossip_time}} set to 3000.
