No. I am not using AMG.

solvers
{
    p
    {
        solver           PCG;
        preconditioner   DIC;
        tolerance        1e-06;
        relTol           0.01;
    };
    U
    {
        solver           PBiCG;
        preconditioner   DILU;
        tolerance        1e-05;
        relTol           0.1;
    };

So, what to do next? Do you think a complete re-compilation/installation solve this issue?

Thanks a lot for your time.

I'm afraid recompilation will not help.

You mentioned the parabolic-BC before. That is the last thing I can think of. Replace that with a normal fixedValue. If the simulation then runs OK then probably the min/max in parallel is the problem
