CPXgetstat / Solution Status: 119 Node file size limit, no integer sol

    Hi, I try to solve an MIP using CPLEX callable libraries in c++. I called CPXgetstat and get a value of 119, which is "Node file size limit, no integer solution." I have been watching the memory usage of cplex through task manager and memory usage is not very large (less than 11,000k). I wonder if something goes wrong. I know the problem is infeasible but I want cplex give a value of 103 (integer infeasible) to the CPXgetstat.

    I also tried to solve the same problem using interactive optimzer and got "MIP - Integer infeasible or unbounded". I believe it is not the same as "Node file size limit, no integer solution." Does anybody know the reason for this and a way to fix it?
