Ahem... the most informative piece I could find reads:

http://www.latimes.com/news/local/la-me-faa16sep16,1,3729661.story

     When the system was upgraded about a year ago, the original [unix]
     computers were replaced by Dell computers using Microsoft software.
     Baggett said the Microsoft software contained an internal clock
     designed to shut the system down after 49.7 days to prevent it from
     becoming overloaded with data.

This appears to be a fine example of a meaningless gibberish, but it seems
that the only valid approximation of what it could originally mean is an
OS problem. Which is consistent with what we know about old Microsoft
OSes.

Sure, the same problem could happen if the application running on that box
used a 32-bit integer to store milisecond count since its launch - but:

  - Why would they use such a ridiculous counter? Applications usually
    do not have to count time on their own, and usually rely on RTC data.
    Counting miliseconds seems futile, though I suppose it could be
    just a matter of an obscure design.

  - Why wouldn't the same code fail on unix previously?

  - Why would they claim again and again that this was an OS "feature"?

It seems that all the claims support the OS flaw version, though of course
it's not a good idea to trust the press on technical issues.

Until we know more, getting into an off-topic, groundless flamewar is not
needed.
