CMIP services was processing a client agent response and needed to reformat the response into an ROIVapdu for transmission as an m-LinkedReply. But the client agent application program did not provide an argument on the response, so the response cannot be formatted as an ROIV-m-LinkedReply. Because of the possibility of this failure, and the fact that agent application programs cannot predict whether the reformatting will be required, it is required that an argument be provided on all responses. This error is only checked when the argument is actually required, so it may appear to be an intermittent problem to the client agent, nevertheless, it is actually a consistent problem.
