jboss-remoting.jar Version

Just a quick question,
What is the version of jboss-remoting.jar which is default with the JBOSS AS 4.2.3 G.A. ?
Is it Service Pack 3 ?

Is it feasible to move on to the latest SP 11 version of the JAR file ?
The reason why I am asking this question is because i am getting an error of lost client connections. This on with some research on goole yielded to a problem with the default jboss-remoting.jar file with JBoss 4.2.3 GA and suggested upgradation to the latestes SP 11.

I wanted to know what are the side effects, if any, if i move to the latest SP 11 ?

Thanks

According to the manifest file:

Specification-Version: 2.2.2.SP8

I do not know if moving to SP11 would break anything.

Well,

I am facing strange issue with my JMS functionality while using the jboss-remoting SP8, after a while all the queues are choked and there are no consumers for the same. But when I am using the jboss=remoting SP4 everything works fine.

Can some one tell me what could be the reason why the queues are getting choked and are not being processed ?
Why am I losing the consumers when I use SP8 jboss-remoting jar files ??

A quick response will be greatly appreciated

as I am stuck here ......
