CoordGmsImpl and GMS error messages
tokobayashi Jan 6, 2005 11:50 PMHi,
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?
