Hi Joern,
this problem has definately nothing to do with your mdp file and is in 
fact not related to GROMACS.
To know what went wrong, it would help to know more about how you 
submitted your job. My guess would be that you killed the shell which 
hosted your job or sth like this.
try submitting the job using "nohup" in front of your "mdrun" command, 
and don;t forget to use the "&" at the end
