Bela Ban commented on ISPN-2697:
--------------------------------

A simple solution could be to have everyone send STABLE messages at desired_avg_gossip, not scaling that value by the cluster size.

Another solution would be to have only the coord process STABLE messages, see https://issues.jboss.org/browse/JGRP-1570 for details.

> When the HotRodServer starts it inserts its record to __hotRodTopologyCache ({{HotRodServer.addSelfToTopologyView(...)}}).
> However, this put may very easily fail - as the command is broadcasted using NAKACK2 protocol, if the message gets lost and there's no following broadcasted message, the message will be not retransmitted and the put operation times out (Replication timeout), which fails the whole HotRodServer startup, all because of one lost UDP message.
