It looks to be a rather generic OpenMM error message, which unfortunately isn't 
very helpful.  I got lots of those, along with random failures, that led me to 
abandon using OpenMM within Gromacs.  Support for OpenMM in Gromacs is limited 
at best, as OpenMM is being deprecated.  Is there any reason you're not using 
the native GPU support from 4.6.1?  The only reason to try to use OpenMM is for 
GPU-accelerated implicit solvent simulations, so if that's what you're doing I 
can understand.  Otherwise, use 4.6.1.
