The error is in the code that converts a 64-bit floating-point number to a 16-bit signed integer... the 64-bit numbers [are] larger... than in the [previous version], triggering an overflow condition...
...[the] backup computer crashes, followed 0.05 seconds later by a crash of the primary computer.
An in-house data reduction program introduced a change in sign for anomalous differences. This program... converted the anomalous pairs... thereby introducing a sign change."
