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

Reducing the timeout on FD_ALL helps: {{new FD_ALL().timeout(3000).interval(1000)}}.

I have to investigate whether this is a bug or not, as the first and second in line leaving at the same time is something that will probably have to solved by failure detection.

I'll look into this this week.

> JGroups does not handle concurrent leaving of nodes correctly. This is a typical use case in cloud environment when scaled down with an autoscaler/manually which we need to handle.
> A simple test can be devised which fails first n (where n>1) nodes from a cluster, reproducer PR https://github.com/belaban/JGroups/pull/397
