[Help-glpk] Memory Allocation Problem in GLPSOL Solver

Dear All,

I implemented an linear integer programming (ILP) formulation using GNU MathProg and run it by using GLPSOL solver in Ubuntu 13.04. 
When I run program with around 2 million integer variables, it is stopped and a message has shown that:

glp_mallc: no memory available
Error detected in file glpenv05.c at line 70
Aborted (core dumped)

However, in used memory road-map in my system, the GLPSOL program just consumes 35% of total memory (3GB).
I do not why the GLPSOL cannot consume more memory even my system still has more than 60% of free memory.
Is there any way to increase memory size allocated to GLPSOL solver.

Please help me!
