I'm not aware of that one, but on a similar vein there was the widespread 
failure of the Patriot systems during the first Gulf War, including the 
attack on the barracks at Dhahran where 28 were killed.

This was caused by the system truncating the values of the clock when written 
to memory, which over a long period of operation resulted in the system 
dismissing incoming missiles as false alarms.

However, this is starting to sound more like the RISKS digest than Beowulf, so 
I'll leave it there.
