FATAL ERROR: Low global exclusion count! System unstable or pairlistdist or cutoff too small.

Dear namd-lers,

I am attempting to perform some coarse grained (CG) MD simulations.
After having successfully coarse-grained my system with the VMD utility
and minimised the structure with namd, I tried to equilibrate the temperature
at 320 K, but I get the following error soon at the beginning of the run:

FATAL ERROR: Low global exclusion count! System unstable or
pairlistdist or cutoff too small.

I tried to increased either the cut-off or the PairListDist or both but
with no success.

Any hint to overcome this problem would be really appreciated.

All the best,
MP
