The primary failure mechanism is that as the device ages, the on resistance of the transistor increases. This leads to inappropriate charge transfer to the capacitor and a drooping output voltage. It is a pretty common issue in analog circuit design when looking at mean time to failure. The underlying mechanism for the increase in on resistance has to do with charge drift in the channel over time, which is not easily remedied.
