After multiple deployments of several apaches and JBoss's i noticed some clients were appearing on some apaches and some on others without much pattern. On inspection I noticed I accidentally changed port="0" to port="1" at start of
<socket-binding name="modcluster" port="1" multicast-address="188.8.131.52" multicast-port="23364"/> on some deployments.
I can't find any documentation explaining this particular value, most seem to reference the multicast ip:poort.
What is significance of this port?
What appeared to be happening is this; once a mod_cluster-manager is started up, if the first client that pinged/responded to him was working on port "0" then he would only serve these contexts. If by luck the first guy to reply was configured on port="1" then he would only serve these contexts.
Is this how it works? Is there a way to pre-configure mod_clusterr-manager to server all contexts regardless of thisport or only a particular port in a more deterministic fashion?
