Remember, if you use FD, there is some time before a dead member is detected and removed from the membership.
Also, if you have multiple channels in the *same* process, then you can have multiple members. Bu this does not necessarily translate to multiple processes.

Subject: Re: [JBoss-user] multiple instances of same node machine in cluster
Thanks for the idea but I am pretty sure there's no old jboss's,(unless
the problem is java|OS level ofcourse).
We kill jboss by kill -9 on the parent id. We get the parent id at
startup like this (snippet from run.sh):
exec "$JAVA" -ms512m -mx1536m $JAVA_OPTS \
-classpath "$JBOSS_CLASSPATH" \
org.jboss.Main "$@" < /dev/null > $jboss_stdout 2>&1 &
echo $! > /usr/local/nick/run/jboss-3.0.6.pid
furthermore, pstree only shows one java process group.
$ pstree -l

If there WERE some badly killed java processes hanging on to the
clustering ports, shouldn't I see some java.net.BindExceptions or such like?
A ghost in the machine;-(
Also when I restart a node I get a nice update on the state of the
cluster - what nodes are present and such. Is there a way to get this
info without restarting a node?
regards,
Nick

Any ideas on how the same server node got to be in the same cluster 4 times? And what effect would this have on the running cluster? here's the server.log output... 2003-02-18 17:20:59,178 DEBUG [org.jboss.ha.framework.server.ClusterPartition] Starting ClusterParti tion: DefaultPartition 2003-02-18 17:20:59,179 INFO [org.jboss.ha.framework.server.ClusterPartition] Connecting to channel 2003-02-18 17:20:59,203 INFO [STDOUT] ------------------------------------------------------- GMS: address is ap01:32876 ------------------------------------------------------- 2003-02-18 17:20:59,331 INFO [org.jboss.ha.framework.server.HAPartitionImpl.DefaultPartition] New c luster view: 7 ([ap03:34203, ap04:34361, ap01:32870, ap01:32872, ap01:32874, ap01:32876]) 2003-02-18 17:20:59,332 DEBUG [org.jboss.ha.framework.server.HAPartitionImpl.DefaultPartition] ViewA ccepted: initial members set ... I don't know if this is relevant but prior to noticing the above in the logs I had trouble restarting the server ap01. On startup log output just stopped at the "GMS: address is ap01:32876" part of the cluster initialization. I ran the default jboss configuration once then was able to successfully start my clustered configuration. I am not sure why this happened either, so if anybody has any ideas? we are running Redhat 7.3 and the sun j2sdk1.4.1_01. thanks for any info. cheers Nick ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user
