[Help-glpk] Too much Memory consumption in GLPK 4.36

[Satnam Singh]

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.
