Was it leaking while the CO2 was connected to the keg or after you removed it?
If it's leaking while the CO2 line is attached, you can lose all of the air in your tank very quickly!
It's not as big of a problem if it leaks only after disconnecting the air. A trick to stopping the post from leaking is to connect the CO2 and crank the pressure to 30 psi. Then if you disconnect the air, the leak should be stopped. The added pressure will usually stop the leak. At that point, you can sometimes back the air off to serving pressure without it leaking again.
