[GSS](7.4.z) Sessions do not expire in cluster after coordinator is killed

XMLWordPrintable

      Follow the steps in reproducer.zip README.md and verify everything is fine on one node. Lets change the reproducer to occure on 2 nodes cluster.

      cp -a standalone node-1
cp -a standalone node-2
./bin/standalone.sh -c standalone-ha.xml -Djboss.server.base.dir=`pwd`/node-1 -Djboss.node.name=host1
./bin/standalone.sh -c standalone-ha.xml -Djboss.server.base.dir=`pwd`/node-2 -Djboss.node.name=host2 -Djboss.socket.binding.port-offset=100

#cluster was formed
#08:20:57,753 INFO [org.infinispan.CLUSTER] (MSC service thread 1-8) ISPN000094: Received new cluster view for channel ejb: [host1|1] (2) [host1, host2]

# Generate the load. It will acces port 8080, thus node-1
./jmeter.sh -n -t /path/to/reproducer/jmeter-testcase.jmx

# Kill the node-1 by Ctrl + C in node-1 terminal.
# You don't need to wait for previous step to be finished.

      You can see on node-2 terminal sessions were rescheduled correctly

      And seems expired as well correctly

      However when verifying from other sources sessions seems still there

      That list should be empty after all sessions expire succesfully.

      Also keep getting 32 active sessions. Sessions does not invalidate. It should be zero.
