Redmine

I don't see any redmine related line in this stack trace, it's difficult to help you find how it happenned.
Can you run a "ruby script/about" ? It could be interesting to have your version infos... And what is the version/configuration of Passenger ?

Thank you for the reply!
How can I access the Passenger configuration? I'm assuming Dreamhost is the only ones able to access that.

About your application's environment

Action Mailer version 2.1.1
Active Support version 2.1.1

rails (2.2.2, 2.1.2, 2.1.1, 2.1.0, 2.0.5, 2.0.2)
rake (0.8.3, 0.8.2)
ruby-breakpoint (0.5.1)

ruby_odeum (0.4.1)
rubyforge (0.4.5)
RubyInline (3.6.7)
rubypants (0.2.0)
rubyzip (0.9.1)

I have also tried setting it to version 2.1.2.
I just noticed it says 'Environment: development', I set the database info in database.yml under production. Is there a way to switch it over to production? I tried un-commenting ENV['RAILS_ENV'] ||= 'production'.

Ok, some updates...

If I run dispatch.fcgi in a terminal it runs fine, outputs the html code and logs this:

Processing WelcomeController#index (for at 2009-03-03 17:50:33) [GET]
Session ID: 8820ef21222d5e09c2f296511875aa3f

Rendering welcome/index
Completed in 0.15917 (6 reqs/sec) | Rendering: 0.01300 (8%) | DB: 0.02726 (17%) | 200 OK [http://:]

But when browsing the website gives me a 500 error in the Apache log.
I tried the webrick server and that works with a browser... but we aren't allowed to run that at Dreamhost.
So, I'm assuming there is a linking issue between the web access and the dispatch.fcgi

Anyone who has some enlightenment on this?

Which version of Redmine are you using ? 0.8.1 stable ?
You should also check redmine logs : if you have a 500 error maybe there will be more explicit messages in those files.

I downloaded the version that is up on the download page, it says 0.8.1... but the SVN url is 0.8-stable.

Normally when browsing to the site, Redmine doesn't write anything to the logs except # Logfile created on Tue Mar 03 22:27:16 -0800 2009.

But I did notice this in the log this time:

I also got this at the same time in the fastcgi.crash.log:

[03/Mar/2009:22:34:24 :: 17794] starting
[03/Mar/2009:22:35:33 :: 17794] asked to stop immediately
[03/Mar/2009:22:35:33 :: 17794] stopping after explicit exit

Ok, if I were you I'd contact dreamhost support ; maybe passenger does not find everything correctly, but it's hard to know without passenger conf (and I presume it's not an easy 3-lines conf if they offer mutualized hosting..)

Yeah, I tried contacted them and they thought I should contact you... LOL.

I'll try them again, thanks for your help.
