This could happen if the receiver in use was subjected to a signal beyond its usable dynamic range. For example, a very strong carrier could mix with another strong station's CW to create "ghost" signals (third-order intermod) for the duration of the carrier. Another possibility is demodulating a strong signal due to a spur in the receiver's local oscillator. Such scenarios are much more likely during heavy contest activity.
