We spend lots of time and money in order to get qnx in
our production system. 
In theory qnx have very nice architecture.

Obviously it is good system if you can live with its limitations.

My experience was that combination of disk I/O, IP networking 
and anything more than average cpu load easily killed qnx.

We then "ported" our code to linux (about 400,000 lines of c),
that was end of the problems.

qnx version was 4.x and linux 2.0.36.
