i think if you use -maxwarn 1, that's fine only for this time only.
Actually you will also get the same prob later at the when using posre.mdp and also mdrun.mdp ..if you still you the old mdp file.
the best way, you should have the new mdp which is generated as an output after you run the grompp
anyway..all the best

I have resolved the problem,please see:
http://www.gromacs.org/pipermail/gmx-users/2008-November/038056.html
Add the "grompp -v -maxwarn 1", That is ok!
I think there is possible something wrong to
the .mdp file. That is not necessary in the gromacs 3.x,
but not in gromacs 4.x.Gromacs 4.x check every err in every step!
Thanks all!

I think your problem below because you are using old mdp file for new gromacs 4.
so now you should rename the mdout.mdp to new.mdp
and you need to change the below line from berendson to V-rescale
; OPTIONS FOR WEAK COUPLING ALGORITHMS
; Temperature coupling
tcoupl = V-rescale
good luck
