You definitely should use a larger cutoff: try 15 Ang. or so.

You system appears to be trapped in a very bad configuration, that it cannot
get out of. Look at what is going on the vicinity of atom 2210 (SG), which
always has a very big local force. The electrostatic energy is very large
and negative, which looks to me like a warning signal. Use LEaP or ptraj to
look for bad contacts in your structure (or do this visually).
