Yesterday, we worked through this behavior and determined exactly what is happening. In our applications, conflict exceptions are always caught and requests are re-tried: they are part of normal expected behavior. This particular conflict, however, is avoidable, and we have implemented a patch to avoid it, and we will include that change in the next release of Durus. The change, in short, makes sure that new oids are all valid in all clients. Thanks very much for the report.
