 Initializing dual steep norms . . .

Hi!

I have been using CPLEX for almost 30 years and this is the first time I get this behavior.

When I solve my MIP, I get this message:

Initializing dual steep norms . . .

and it stays stuck there for hours without doing anything else.

I have tried to modify the Markowitz tolerance , change the dual pricing, even modify my MIP in a way that I first solve with a big chunk of my constraints and add the capacity constraints afterwards, and nothing works.

Can you help me?

Thanks
