             Summary: GMS: reduce likelyhood of merges on concurrent new member startup
                 Key: JGRP-2412
                 URL: https://issues.jboss.org/browse/JGRP-2412
             Project: JGroups
          Issue Type: Enhancement
            Reporter: Bela Ban
            Assignee: Bela Ban
             Fix For: 4.1.9


When multiple new members are started concurrently, and no coord is present yet, different clients get different discovery results, and this may lead to merging.

If we have no coord, we could run the discovery protocol multiple time, *with the current members list being cached*, and then might end up with a more similar list of new members.

This could be governed by an additional attribute in {{Discovery}} ({{num_discovery_runs}}?)
