How to minimize it ? =========== COMMENT ============= Did read my other mail concerning how to manage logging? I thought I was pretty explicit (and gave an example). If my example for logging.properties was unclear, please ask specific questions (to the list). If you want less logging, then turn down the levels. See the following documentation: http://tomcat.apache.org/tomcat-6.0-doc/logging.html#Using_java.util.logging_(default) =========== COMMENT ============= > > Below are the logs of catalina.out.

Hence, if you wish to subdivide your clusters, you can do this by changing the multicast IP address or port in the <Membership> element. In other words, if you want multiple clusters change either the multicast address here: <Membership className="org.apache.catalina.tribes.membership.McastService" address="228.0.0.4" port="45564" frequency="500" dropTime="3000"/> to a different multicast address, or change the port in the above to a different port. The multicast address / port establishes the cluster group. The above snippet is from one of my server.xml files. You might also want to read up on how multicasting works. =========== COMMENT ============= > > > > INFO: Replication member > added:org.apache.catalina.tribes.membership.MemberImpl[tcp://{-64, -88, 3, > 18}:4000,{-64, -88, 3, 18},4000, alive=18507474,id={25 -66 -54 110 84 -96 > 79 -74 -84 -106 122 -65 -121 9 -16 5 }, payload={}, command={}, domain={}, ] > Apr 5, 2012 12:31:10 AM > org.apache.catalina.tribes.group.interceptors.TcpFailureDetector > performBasicCheck > INFO: Suspect member, confirmed > alive.[org.apache.catalina.tribes.membership.MemberImpl[tcp://{-64, -88, 3, > 18}:4000,{-64, -88, 3, 18},4000, alive=18507474,id={25 -66 -54 110 84 -96 > 79 -74 -84 -106 122 -65 -121 9 -16 5 }, payload={}, command={}, domain={}, > ]] > Apr 5, 2012 12:32:10 AM > org.apache.catalina.tribes.group.interceptors.TcpFailureDetector > memberDisappeared > INFO: Received > memberDisappeared[org.apache.catalina.tribes.membership.MemberImpl[tcp://{-64, > -88, 3, 18}:4000,{-64, -88, 3, 18},4000, alive=18507474,id={25 -66 -54 110 > 84 -96 79 -74 -84 -106 122 -65 -121 9 -16 5 }, payload={}, command={}, > domain={}, ]] message.
