Hey everyone,

I'm running my commands blockMesh, surfaceFeatureExtract, decomposePar etc. and then I run the command:

mpirun -np 6 simpleFoam -parallel

and it always works.
Then I reposition my objects and my blockMesh and execute the same commands and when I execute "mpirun -np 6 simpleFoam -parallel" I get several warnings and simpleFoam stops working:

WARNING: Linux kernel CMA support was requested via the
btl_vader_single_copy_mechanism MCA variable, but CMA support is
not available due to restrictive ptrace settings.

The vader shared memory BTL will fall back on another single-copy
mechanism if one is available. This may result in lower performance.

I've tried it several times and checked my system folder.

Thanks for any help,
