Bela Ban commented on JGRP-1559:
--------------------------------

This method is called every 2 seconds:

    private void startFdMonitorIfNeeded(FD fd, JChannel channel) {
        boolean moreThanTwoMembersInCluster = channel.isConnected() &&
channel.getView().getMembers().size() > 1;
        if( moreThanTwoMembersInCluster ) {
            if( !fd.isMonitorRunning() ) {
                fd.startFailureDetection();
                LOG.error("FD forcefully started for nodeId = " +
channel.getName() + ", cluster = " + channel.getClusterName());
            }
        }
    }

After 65 min it reported that task was not running.

> FD.isMonitorRunning() is sometimes false even when the membership is > 1. Probable cause is restartMonitor() will stops the running monitor, but doesn't start a new one if ping_dest == null.
> Need to investigate concurrent updates to pingable_mbrs and ping_dest.
