There were some reports of strange things happending with php's
readfile(). Personally I believe it's php issue (probably
configuration/programming one - e.g. memory limit reached due to
output buffering activated and script terminated or something like
this). But I've never seen any debug info to prove this point.

If you are able to reproduce it - could you please build debug log
and post it?

Of course it's much better to use X-Accel-Redirect instead as
already suggested.
