Deatch Match Gravity Setting

Hello,

I am trying to create a low-gravity killbox type environment with the Black Mesa dedicated server.
sv_gravity works, however, once it gets below a certain value (I think 400), I can no longer jump. Is this a known bug, or maybe intended behavior?

Thanks for any help.
