More pertinent information would be a description of your system, which force 
field you're using, as well as which water model you are using.  The error comes 
from a mismatch between these latter two items.  HW is a water hydrogen for most 
force fields, but the Gromos96 series use H.  I suspect you've mangled the 
topology in some way such that you've broken the internal mechanics of whatever 
force field you're using.
