How do I stop leaking water - GE Profile Model TFX25PR refrigerator?

The refrigerator is side by side style with a door mounted ice and water server. Two or three times a week I find a pool of water across the front of the refrigerator. There are no apparant leaks in the water supply connections, or ice maker. Where does the water originate and should it drain somewhere? I do find ice on the bottom of the freezer compartment.
