I think this is a bug.you should inform oracle and get patch from them to solve the problem.I think the problem is with ( KSEDMP) service Layer.Not sure!!.
Anyway you consult with oracle customer service people to resolve the problem
This error is a known bug for 8.1.6. As soon as you upgrade to 8.1.7. or above, it should eb solved.
