To use *DeltaManager* with unicast (static membership), the Tomcat 8.5 documentation (https://tomcat.apache.org/tomcat-8.5-doc/config/cluster.html) states that the channelStartOptions should be equal to *3*.
However, the value should be left as the default when using the *StaticMembershipService* according to the Tomcat 9.0 documentation ( https://tomcat.apache.org/tomcat-9.0-doc/config/cluster.html). Why does this distinction exist? Sincerely Manak Bisht
