I also noticed similar behavior with large files with Varnish 3.0.1.
Today, when I tried to do large files.. Here's a wget run.

2011-10-07 17:18:59 (442 KB/s) - Connection closed at byte 28062437. Retrying.
2011-10-07 17:20:03 (486 KB/s) - Connection closed at byte 59268331. Retrying.
2011-10-07 17:21:07 (500 KB/s) - Connection closed at byte 90762224. Retrying.

varnishlog craps out with the following message:
   11 Debug        c Write error, retval = 28062720, len = 107637870,
errno = Success

Indeed, wget does do Range: requests when the connection dies, but a
different machine (OSX with curl and firefox) would end the download
thinking the file was done.

Could be timeouts, but I'm not sure why they would happen in this case.

oh on a side note it seems maybe the 3.0 varnishlog format isn't
compatible with the 2.x one?
