Hello guys!
We are trying to test Tomcat clustering but we are getting some problems.
Sometimes (Log2) everything works fine but in other cases the cluster
doesn't work (Log1). The only difference is the time that we wait after we
shutdown a node. When we make a request after shutdown a node, cluster
doesn't work, but if we wait more time (1 minute more or less), the cluster
works fine and we can proceed making requests.
