Comment(by ntang):
It shouldn't have been a timeout... here's how long it takes when I query
Apache directly:
{{{
[root at cc20-43 ~]# time curl --head --header "Host: [snip]"
cc85-45:80/files/2010/10/HM-33-2-WEB.mp3
HTTP/1.1 200 OK
Date: Mon, 15 Nov 2010 14:07:25 GMT

}}}
As you can see, it's returning the file in around a quarter of a second.
We are planning on upgrading to 2.1.4 to see if it fixes it, but right now
there's no 32 bit RPM, so we need to build one ourselves and fixing the
problem quickly was our top priority.
(For now we're just routing requests for mp3 files straight to Apache,
around Varnish, and that's kept things moving smoothly, as we don't get a
huge number of requests for them and we've got the capacity there. But
obviously, we'd like Varnish to serve all of this content eventually.)
