My company makes an rails app that we serve using nginx. I’m trying to
make a
livecd that we can use distribute the app to customers. This has gone
remarkably smoothly so far, with one small sticking point. When booted
from the
CD, nginx serves the rails content just fine, but won’t serve any
images. I get:
2009/03/06 18:13:43 [crit] 7474#0: *1 sendfile() failed (22: Invalid
argument)
while sending response to client, client: 192.168.1.147, server: ubuntu,
URL:
“/images/chart_ignored_hover.gif”, host: “192.168.1.113”, referrer:
“http://192.168.1.113/stylesheets/application.css?1233944282”
2009/03/06 18:14:16 [crit] 7474#0: *2 sendfile() failed (22: Invalid
argument)
while sending response to client, client: 192.168.1.147, server: ubuntu,
URL:
“/images/bug.png”, host: “192.168.1.113”
The permissions on the images directory are right, and it will serve
other
static content (e.g. public/404.html). If I edit the config file and
set
“sendfile” to “off”, the images show up. My best guess is that some
system
config file is getting mangled, or that something is being mounted
differently.
Can anyone offer a suggestion as to what I should look at next? I
checked the
(english) documentation, and I can’t figure out what enabling sendfile
does or
why I would want to use it anyway.
Some details:
nginx version is nginx/0.5.33. OS is ubuntu 8.04, kernel version is
2.6.24-23.
LiveCD is using casper, and mounting / using unionfs. error_log level
is at debug.
