Velocity after heating

Hi all,

 I have gradually heated my system over some ps to 300k, and when Iím
trying to apply position restrained MD using this script:

fixedAtoms on
fixedAtomsFile fix_mysysteme.pdb ;# only fix backbone.
fixedAtomsCol B
fixedAtomsForces on

 I have received the following error message (see attached .log file):

ERROR: Atom 3429 velocity is -16402.4 -14246.5 -6641.39 (limit is 10000)

 Did some one know why the velocities exceed its limit and is it possible
to change this limit?

Thanks for any help.

Mustapha
