Right - so you have constaints regardless of the .mdp file option set.

Now you will need to look at strange energies and/or bad contacts.
You may need to decrease nstener or nstxtcout to see the problem starting
before the simulation crashes. Also, you may need to disable the output
buffering by setting LOGBUFS=0 (environment variable).
