The problem was within a dll called by LabVIEW. Do you use any third party drivers?
Since this occurred after 2 hours, there could be several possibilities.
Was this a random event or is it reproducible and occurs always after 2 hours?
If reproducible: Do any of your data structures grow without bounds over time? How is the memory usage over time? Are there any counters that "wrap around" after two hours?
If not reproducible: Could have been just a random event (e.g. memory corruption by cosmic rays, gremlins, or power surges, marginal hardware, failing computer components, etc.). The possibilities are infinite. 😞
