    Hi Krzysztof,

    Is it possible that this run is hitting your machine's memory limit? It is possible that the OS starts swapping memory to not abort the process which as a result slows down the affected process tremendously.

    If it is a memory issue, you might want to have a look at How do I avoid an out-of-memory condition?

    Best regards, 
    Jaromił

    First Question

    I would also add, to what Jaromił wrote, that your model is extremely large. I would suggest you reconsider the formulation of your model.

    Judging by the other questions you asked, I believe you are trying to solve an inventory optimization problem. Perhaps this paper could serve as an inspiration.

    Best regards
    Jonasz
