Execution group is getting restarted when a message is passing through JMS Output Node in Version 7.And there is no specific JMS error in Logs and stderr also.
JMS Provider is JBoss and all the other details are same which are used in V6.1.
Properties set are:
JMS Provider : JBoss
Intial Context Factory : org.jnp.interfaces.NamingContextFactory
Location Binding : jnp://10.10.100.35:1199
Connection Factory Name :ConnectionFactory

And the respective JBoss related jar files are placed in shared-classes folder

The same is working fine V6.1


Is there is any issue because of Version change??

Look at the stderr and stdout files in the execution group directory.

The broker should also create a separate file (FFST or FDC) for each abend. Look for that first.

For the usertrace, look for messages where the broker is restarting, and see what was happening before that point. The statement that actually caused the abend might not have made it to the usertrace, but the statement before that should have; that should help narrow down at least where the abend occurs.

It's not normally useful to generate a service trace, unless IBM specifically asks for one; they are better able to read it than most users.

Not to state the obvious, but have you confirmed that the flow isn't somehow creating an infinite loop or something that looks like an infinite loop (where the message just goes back to the input node)?
