P.S. Isn't it something we can tweak at server/default/deploy/jboss-messaging.sar/remoting-bisocket-service.xml ?
P.P.S. is remoting 2.5.0 GA compatible with my configuration?
The change for JBREM-1165 "Reduce log level of "received new control socket for unrecognized listenerId" message" has been made for future releases 2.2.3.SP2 and 2.5.2.SP1. I believe that people have been using Remoting versions 2.4/2.5 with AS 4.3.2 GA and jboss messaging 1.4, but I don't know that the combination has ever been tested, at least by JBoss people.
I plan to release 2.5.2.SP1 in the next couple of days, so you could try it if you like. 2.2.3.SP2 probably won't be released until around the beginning of next February, but you could always build it yourself.
I forgot to mention that the 2.4 / 2.5 versions of Remoting might have additional features and some improvements under the covers, but should be compatible with and substitutable for the 2.2 versions.
