    Hi

    could you try to add

    execute
    {
    cplex.threads=1;
    }
    


    at the beginning of your .mod file ?
    This will tell cplex to use only 1 thread and will reduce the memory usage.

    Regards

    I changed the work directory. it worked for me. it used to give me that error even though i had sufficient memory in default location.

    execute PARAMS {
    cplex.WorkDir = "E:/newfolder";
    }
