I was solving a large MILP problem. On a Linux server with Gurobi 9.1.2, the solver is always stuck solving the root node LP. However, I didn't have this problem when I tested the same problem on my windows machine (with much smaller RAM and CPU power than the Linux server) with Gurobi 9.1.1. Could the version be the reason for the difference?

Log from the Linux server:

Log from the Windows laptop:

  The issue has been resolved. It was an out-of-memory condition. Reducing the number of Threads reduced the amount of memory consumed. More details can be found in How do I avoid an out-of-memory condition?
