With the mentioned below options I get the following error:

This usually means that your system is not well equilibrated.


But it does not occur immediatly but only at step

Is there something wrong with my temperature coupling?


I doubt it. Decrease your timestep (as I've said twice now) and try again with something sensible for dt.
