----------------------------------
Summary: RELAY2: delay shutting down bridge
Key: JGRP-1846
URL: https://issues.jboss.org/browse/JGRP-1846
Project: JGroups
Issue Type: Bug
Affects Versions: 3.5
Reporter: Dan Berindei
Assignee: Bela Ban
A simple test that starts 2 sites x 2 nodes each and shuts them down in order shows a 1
second delay when shutting down the last node in the first site (B):
public void testCoordinatorShutdown() throws Exception {
a=createNode(LON, "A", LON_CLUSTER, null);
b=createNode(LON, "B", LON_CLUSTER, null);
x=createNode(SFO, "X", SFO_CLUSTER, null);
y=createNode(SFO, "Y", SFO_CLUSTER, null);
Util.waitUntilAllChannelsHaveSameSize(10000, 100, a, b);
Util.waitUntilAllChannelsHaveSameSize(10000, 100, x, y);
waitForBridgeView(2, 20000, 100, a, x);
a.close();
Util.waitUntilAllChannelsHaveSameSize(10000, 100, b);
b.close();
waitForBridgeView(1, 20000, 100, x);
x.close();
y.close();
}
And the relevant logs:

Note that while this happens on a background timer thread, the shutdown is delayed
nonetheless because {{TP.destroy()}} waits at least 500ms for all the timer threads to
finish ({{TimeScheduler3.stopRunning()}}. Perhaps that should change as well, so that
timer threads are interrupted and finish immediately.
