Hello,
It appears as though the problem surfaces with newer Google Chrome
browser using both Adobe 8 and Adobe 9 plugins under Window, when
dealing with a linearized PDF. According to the original report the
problem may also exist under Windows with Firefox and using Adobe 8
plugin.
I don't have that setup myself, but that is what I saw when I ran a
packet sniffer to capture data from an individual who was seeing
problems:

that I eventually traced to the varnish layer. The behavior he was
seeing was due to his Chrome browser sending
Range: bytes=1-1,2594-4095
when encountering one of these PDFs.
