    CoordGmsImpl and GMS error messages

    Toshiya Kobayahsi Newbie

      Hi,

      I set up 4-nodes cluster and tested an application with heavy load.
      Environment is JBoss4.0.0, JDK1.4.2, Redhat Enterprise AS3.0. Requests are load-balanced by Apache2(worker)+mod_jk2.
      During the test, some error-logs were found in each node.

      node1:

      Loglevel was limited to ERROR. So, I tried again after changing loglevel to WARN for jgroups, but I couldn't reproduce this problem.

      There are three kinds of messages:
      1. "[CoordGmsImpl] handleJoinResponse() should not be invoked on an instance of org.jgroups.protocols.pbcast.CoordGmsImpl"
      2. "[CoordGmsImpl] mbr 192.168.61.167:32776 (additional data: 19 bytes) is not a member !"
      3. "[GMS]
      [192.168.61.165:32782 (additional data: 19 bytes)] received view <= current view; discarding it (current vid: [192.168.61.167:32782 (additional data: 19 bytes)|1], new vid: [192.168.61.167:32782 (additional data: 19 bytes)|1])"

      What causes these messages?
      This problem has an influence on the reliability/performance of the application?
