lighttpd, fcgi, rails and child exited with status 9, 1, 2, 3 or X
Ok, these errors are not good. They didn’t tell much about what happended.
But you can’t do as I did. Don’t wander on the dark side of the system…
Just try to execute your FCGI as your lighttpd did.
Find your lighttpd user in lighttpd configuration file (debian: /etc/lighttpd/lighttpd.conf).
On my configuration I see:
server.username = “www-data”
# cd /my_rails_root/public
# sudo -u www-data ./dispatch.fcgi
Read what’s happen and solve.
