No, the problem is not too large. You can see in your glpsol logs that the problem is formulated and glpsol is trying to solve it.The MIP problem is just hard to solve using the algorithms implemented /used in GLPK. Try to solve this MIP problem using CBC - MathProg. Here's how to compile CBC with MathProg.
