Real Encoder recording Limbaugh on two different machines both locked up today at the same time, after working unattended flawlessly for years.

A little investigation reveals that the "unix" time used by XP rolled over its last 25 bits to zero at 17:40:16 GMT, which matches to the minute where the real encoders locked up.

That must be the cause of the impossible coincidence. Maybe they use a 24-bit time for internal comparisons.
