Incomplete headers

mgreenly · December 21, 2005, 1:09pm

Hi,

I wanna use Rails on a SuSE server with apache. Everything should be
installed correctly, but when running the application I get this in my
apache log:

FastCGI: comm with server
“/srv/www/htdocs/web4/html/rails/public/dispatch.fcgi” aborted: idle
timeout (60 sec)
FastCGI: incomplete headers (0 bytes) received from server
“/srv/www/htdocs/web4/html/rails/public/dispatch.fcgi”

When using the WEBRick server it works. This is my virtual Host Config:

ServerName myServer DocumentRoot /srv/www/htdocs/web4/html/rails/public ErrorLog /srv/www/htdocs/web4/html/rails/log/apache.log

FastCgiIpcDir /tmp/fcgi_ipc
FastCgiServer /srv/www/htdocs/web4/html/rails/public/dispatch.fcgi \
   -initial-env RAILS_ENV=development \
   -idle-timeout 60

<Directory /srv/www/htdocs/web4/html/rails/public>
    Options ExecCGI FollowSymLinks
    AddHandler fastcgi-script .fcgi
    AllowOverride all
    Order allow,deny
    Allow from all
</Directory>

I’ve already tried a lot. The /tmp/fcgi_ipc has the correct permissions
and the cgiserver-setting seem to work, because the timeout in the error
message is 60 seconds too.

I’ve also downgraded vom fcgi 0.8.6 to 0.8.5, because I read, that there
is a bug in the current version.

When running the dispatcher manually, I get this:

chicago110:/srv/www/htdocs/web4/html/rails/public # ruby dispatch.fcgi

And in the fastcgi.crash.log I get:

[21/Dec/2005:13:07:39 :: 6435] starting
[21/Dec/2005:13:07:39 :: 6435] terminated gracefully

But I can’t run it in the browser. Any idea why not?

Greetings

What does your development.log say? Is it writeable by the apache user?

Hi,

strange, the log is empty. But it has the needed permissions:

-rw-rw-rw- 1 web4 ftponly 1 Dec 21 17:07 development.log

This should be enough, or not?

Yes. What i tested on my machine is, that if you delete development.log
and run the dispatch.fcgi script manually the logfile should be
recreated. If it does not on your system, Rails is never starting the
boot process, that means your problem is lying a little bit deeper.

Hi,

ok I tried it out. The development.log was created automatically.

Any further ideas, what I can do?

Got the same problem; fastcgi gets really unstable after few requests.
Running Rails 1.0 and latest freebsd ports for apache and mod_fastcgi

In apache error log:

My problem was that the dispatch wasn’t getting the

require ‘fcgi_handler’

so I had to hand copy this from my rails gem directory to the apps lib/
directory and it all worked. Obviously not the best solution, but this
was the root of the problems.
