Two possibilities :
Zero absolute temperature- Then, molecules will have zero energy and will stay stationary. They wont collide with container boundary and thus will exert no pressure.
No mass- In absolute vacuum condition when all the air has been pumped out. Such situations prevail in outer space.
Therefore, momentum transfer must be zero either by zero mass or by zero velocity.

The theoretical temperature is determined by extrapolating the ideal gas law by international agreement absolute zero is taken as - 27 3.15 degree on the Celsius scale which = 2 - 45 9.67 degree on the fahrenheit scale
