DearAll,
when I am running NVT equilibration phase i am getting following error
Back Off! I just backed up step0c.pdb to ./#step0c.pdb.4#
Wrote pdb files with previous and current coordinates
starting mdrun 'Gromacs Runs On Most of All Computer Systems in water'

WARNING: Listed nonbonded interaction between particles 6483 and 6507
at distance 3f which is larger than the table limit 3f nm.
This is likely either a 1,4 interaction, or a listed interaction inside
a smaller molecule you are decoupling during a free energy calculation.
Since interactions at distances beyond the table cannot be computed,
they are skipped until they are inside the table limit again. You will
only see this message once, even if it occurs for several interactions.
IMPORTANT: This should not happen in a stable simulation, so there is
probably something wrong with your system. Only change the table-extension
distance in the mdp file if you are really sure that is the reason.
if any one have solution for that. please let me know

You haven't told us what your system is, what force field you're using, or what
prior preparation steps you have done (energy minimization and its outcome).
Without vastly more information, no one can help you very effectively. These
sorts of problems are posted to this list almost daily, so please spend some
time in the list archive. There is certainly something helpful among the
thousands of posts describing unstable systems and blowing up.
