I'm working with the cvs tagged 5.5.10 version of tomcat to check out
some clustering fixes.
When I bring a 2nd server into the pool, I get this exception repeated
every time an mcast packet is received:
==CUT==

==END CUT==
Here are the relevant lines of code from McastMember.java:
==CUT==
byte[] domaind = new byte[dlen];
System.arraycopy(data, nlen + 24, domaind, 0, domaind.length);
==END CUT==
I added some debugging to figure out the length of the data. The
exception occurs because data.length is 23. Obviously 23+24 is going to
throw an ArrayIndexOBE.
My question is.. is there a configuration thing that is causing data to
be sent to be less than the desired length? It appears the data is not
coming in in the format expected.
Thoughts?
Your post is OT on this mailing list, but I thought I would play a
little with the clustering.
This works for me, with this config:
className="org.apache.catalina.cluster.tcp.SimpleTcpCluster"
managerClassName="org.apache.catalina.cluster.session.DeltaManager"
expireSessionsOnShutdown="false"
useDirtyFlag="true"
notifyListenersOnReplication="true">
className="org.apache.catalina.cluster.tcp.ReplicationValve"
filter=".*\.gif;.*\.js;.*\.jpg;.*\.png;.*\.htm;.*\.html;.*\.css;.*\.txt;"/>
className="org.apache.catalina.cluster.session.ClusterSessionListener"/>
The domain feature for membership is new in this release (which caused
the data packets sent to change).
I recommend trying tomcat-user, or filing a bug if you can give working
instructions on how to reproduce the problem.
