[gmx-users] Chracter buffer size too small

[Olaniyi Yusuff]

Dear gmx-users,
I am having problem with grompp during minimization of my 
protein-solvent system
Please i want to know what the error message character buffer size too 
small from grompp in the minimization stage means and what step is 
needed to correct this error.
below is the .mdp file used,
