Hi Biswajit,
It would be helpful to get a bit more information about the issue you are having. What error are you seeing? Could you provide a minimum working example? It would be best to post a short self-contained code to reproduce the issue you describe.

Actually, this is a transportation problem... working through different layers of sources and destinations. it worked up to a particular node, but when the problem gets bigger, and variable numbers reach around 68000, the problem gets slowed up.

To address an out-of-memory error, there are some good tips in How do I avoid an out-of-memory condition? In particular, it is helpful to set NodeFileStart to 0.5. This tells Gurobi to compress the branch and bound tree and write to disk.
