More infomation about your system would help narrow down the exact cause but my guess is you have a zoned system with a control box inside your house. If this is the case, and it was only one zone that was on at the time, then it is either the valve that needs fixing or your control box has an issue.

If it is your valve, which I find more likely due to the brief cold snap we just had, the problem could be the O-ring (not likely), your pressure release valve opened(the little tiny screw type thing on the side of the big valve), or your whole valve is shot. The more I think about this, the more I think it is probably the pressure valve, which was opened not by freeze/thaw, but by some prankster kids. If your box outside isn't locked, or there was any evidence (footprints) this would be highly likely

The other option is a short causing a closed circuit in the control box, which is an easy thing to test for. Just switch the wire running to that zone outside (match the colors, or guess and check) with one that isn't alwasy on.

Anyway, if this doesn't help or youhave some more specific info as to your system (make of external components, make( AND MODEL ) of control box, type of system, rain sensor installed, age of system, installer), I may be able to help you out a bit more. And possibly walk you through troubleshooting it.
