My understanding of keyboard jogs is that a "key pressed" event for the up-arrow stops any active Y axis jog, and then starts a +Y jog. A "key released" event for the up-arrow stops any active Y axis jog. Likewise for the down-arrow.
It sounds like LinuxCNC isn't seeing the "key released" events. Does hitting the escape key stop one of these "runaway jogs"? The escape key is supposed to generate an "ABORT" command to motion, which should stop the movement. Whether or not that happens might be a clue.
