That's a rather strange object ID. Do you really have over 10,000 TNObject scripts present in your scene? As a rule of thumb, if you have more than a few of them per scene, you're likely doing something very wrong. How are they created? Do you have something creating them at edit time?
Make sure to delete server.dat file if you have it. If you created a channel with a persistent flag set, all your previous RFC calls are still going to be present, which is a problem if you changed TNObject IDs.
