Hi,
I am using GLPK 4.36 to solve MIP problem. My problem contains approx. 1700 integer variables. I ran GLPK with a timeout of 1 hour and it provided a sub-optimal integer solution. Then I ran the same problem with timeout of 5 hours. but after around 2 hours of run, it crashed, saying that malloc is un-able to allocate memory. And when I saw the logs, it consumed around 2 GB memory just before crash. I suppose that, this is due to a potential memory leak. ( or this is because the size of the problem is very big so the data structures consumed this much memory ?) Thanks.
