------------------------------------

             Summary: Partitions can take up to 2 minutes to merge
                 Key: WFLY-9420
                 URL: https://issues.jboss.org/browse/WFLY-9420
             Project: WildFly
          Issue Type: Bug
          Components: Clustering
    Affects Versions: 11.0.0.CR1
            Reporter: Radoslav Husar
            Assignee: Radoslav Husar


Using the {{MERGE3}} protocol, it can take significantly longer than {{max_interval}} for merge to happen. 

The info sender interval is up to 45 seconds
{noformat}
        public long nextInterval() {
            return Math.max(min_interval, Util.random(max_interval) + max_interval/2);
        }
{noformat}

and the view consistency checker interval is 48 seconds

{noformat}
    protected long computeCheckInterval() {
        return (long)(max_interval * 1.6);
    }
{noformat}
