--------------------------------------------------------------
We have migrated our application from JBoss-4.0.3SP1 to JBoss-5.1.0.GA. We are using ejb2 & messaging. The messaging is highly available part of the application. In our application, we have not touched/modified/overridden any functionality/implementation related to jboss messaging & remoting and rely on default implemntation/functionality provided by JBoss AS. We have only created multiple topics using org.jboss.jms.server.destination.TopicService.
Following exception appears on server side:
Application error detected : WorkerThread#2[127.0.0.1:2440] exception occurred during first invocation
java.io.EOFException
at org.jboss.remoting.transport.socket.ServerThread.processInvocation(ServerThread.java:693)
at org.jboss.remoting.transport.socket.ServerThread.dorun(ServerThread.java:524)
at org.jboss.remoting.transport.socket.ServerThread.run(ServerThread.java:232)
On further analysis it has been found that
(here we are talking about <jboss_home>\server\<config>\deploy-hasingleton\+*messaging\remoting-bisocket-service.xml*+)
1) if clientLeasePeriod is set to 0 then exception disappears
2) if clientLeasePeriod is non-zero then
a) if clientLeasePeriod > validatorPingPeriod
and either clientLeasePeriod or validatorPingPeriod or both are not divisible by 10
then exception disappears
b) if clientLeasePeriod > validatorPingPeriod and divisible by 10
then exception appears
c) if clientLeasePeriod < validatorPingPeriod then exception appears (this situation is justifiable as explained above in this forum/discussion).
Please help me to understand the reason for the issue & the feasible solutions for the same. Right now we are able to temporarily fix it using scenario 2)a).
