    I need to resolve the problem (with some modification) to generate cut in cut callback. I declare another "ilocplex" class in the cut callback, but the program somehow stop at the line of "IloCplex Cplex" in the cut callback. Ant the cpu usage there is also zero. I don't know why.

    Anyone knows the answer? Thanks very much~

    No crash, nothing. Just stops?
    What version/port of CPLEX are you using?

    What about my other questions? What is the exact statement that causes your program to hang? Maybe you can even post your cut callback code here? Or at least the relevant part?
