Check again for warnings, and pay attention to them :-)

Your system is blowing up, probably because it is poorly formed or 
equilibrated. The maximum force post-EM looks far too large. See 
http://wiki.gromacs.org/index.php/Errors and 
http://wiki.gromacs.org/index.php/blowing_up. Try some tutorial material 
on a similar system if you haven't already.
