Random Leak from Faucet - Perlick 630SS

[403Brewer]

So I came home today to the wonderful aroma of spilled beer in my apartment, turns out one of the taps on my kegerator leaked while I was gone (only about a pint, not a massive mess). I hooked up the keg last night, carb'd at 12 PSI and thats where the reg is set right now. I poured a pint last night, everything was fine after and when I woke up. Any thoughts on what could have happened??

There is no drip or other leak I can see, and the tap is only about 5 months old.

Who knows. Do you have a cat??

When was the last time you took the faucet apart and cleaned it well?

Did you drink a bunch the night before and not closed the tap all the way?
