For a proper answer, suggest you post on the Remoting forum. It looks to me like there's no real issue here, just a case of Remoting logging at too high a level (should be TRACE not DEBUG). In that case, just limiting the log category is fine. (If there were a serious problem, there'd be logging at a higher level than DEBUG and/or you'd be seeing issues in your application.) I believe what happened here is once you enabled clustering, the getLocator() method is returning a different value, and hence MarshalFactory.getMarshaller(getLocator(), getClassLoader()) is returning a different value.
