    Hi,

    we encountered a strange problem with CPLEX 12.7.1.
    Running CPLEX with 2 threads it manages to solve the MIP to optimality within a few minutes.
    Running CPLEX with just 1 thread with a time-limit of two hours it got stuck in preprocessing and does not find any solution (neither primal nor dual).

    Are there any known issues related to that problem?

    Are there any work-arounds for 1 thread?

    Both runs work fine with CPLEX 12.6.2.

    Please find the log-files enclosed.

    Cheers
