OK so there's no indication from GROMACS that it's experiencing trauma 
within the simulation. So now you need to try to restart close to the 
point you saw problems to see if the problem is reproducible. If it's 
not reproducible, then my guess, as last time, is that an NFS share is 
becoming unavailable, or some such. There are lots of other 
possibilities - a bug in GROMACS seems unlikely at this stage.
