Either upload a sample that reproduces the problem as Dominico suggested, or at least provide more information about how you are calling CPLEX, including the API you are using and the code segment that prints out the error message. And when you say you are solving a problem using Benders' decomposition, are you using the automated Benders feature in CPLEX or implementing your own version of Benders?
