Shouldn't the positive pressure (10psi Co2, 40*F) keep the air out? I understand the physics side of it, no matter the pressure some air molecules will get in, but not that much that quick.

Check for a bad o-ring at the top of the dip tube. You might have a small leak of CO2 into the dip tube.
Thanks for the advice? The pressure in the keg (and the whole system) is 10 psi. The temperature is 40*F. I am going to throw a computer fan in there. Maybe that will help. My lines are about 5 ft. Any other suggestions?

Clearly, it's not ingress of air, it's CO2 coming out of solution as mattd2 explained.
Two ways that happens: either the CO2 pressure being applied is lower than that required to maintain the carbonation level of the beer, or there is a temperature gradient between the bottom of the keg (where the dip tube draws) and the fittings and tubing at the top of the keg. Tubing length or diameter has nothing to do with this particular phenomenon...
Cheers!
No dice. Still have bubbles in the line and a foamy pour. Just kegged a cider and a stout; gonna let them carb up and see what happens. Temp at 39 (on top and bottom) and pressure at 9.
Changed Lines to 10ft. And put a fan in the bottom of the fridge to even out the temp. I'll report back tomorrow!

Any chance the liquid disconnect top disassembly screw being loose can cause this? Wondering if it being loose can allow air to get sucked in through it with the pressure of the liquid being pushed through.
Rev.
What size (inner diameter) are your drink lines?
As Max said earlier you lines look way too big for only 5'
My post didn't update so I didn't see all the other replies. They are 3/16 bevflex lines. Started at 5ft changed to 10ft. It's running at 10psi. I will replace the ring tomorrow and go from there.
Yes, there are tiny bubbles forming immediately after a pour, they then congregate to either side of lines (shank and post) after a while.
Edited to add: this is my 10th keg or so and the first time it has happened. All the while having 5ft lines.

I chill the beer to serving temp. I set it 30 and roll it for 5 minutes. Then I turn the gas off and release the pressure. I set it back to serving pressure and put it back in the fridge. Usually ready to drink within a day or 2 after that.
I have 2 thermometers, one on top and one on bottom.

I have 2 other kegs and bottles in the fridge and nothing else is froze. I can still drink from the keg with no issues and it tastes great. The temp in the fridge has only read 38 at its lowest. What leads you to believe its froze? I'll open it up and take a look though.

This is the problem. You should stop doing that. That's a terrible way to carbonate. It's incredibly easy to force too much carbonation into your beer doing it this way (which you did on this one).
