so that restarting applications would work seamlessly on NFS shares. On lower traffic sites, you can usually still visually see the application restarting by "priming" a page dreamhost rails version (loading it a couple times in your browser), touching the restart.txt file and then loading that page again. It should take a noticeably longer time to load than it had the previous couple of times. This won't really work on live sites that are getting traffic though as it's entirely possible another person's request restarted dreamhost django the application by the time you test it yourself. Broken pipe error If you get an error message mentioning a broken pipe with the exception class PhusionPassenger::Railz::ApplicationSpawner::Error as depicted in the image, you're most likely running into memory limit problems. What's happening is the request being processed by Passenger caused your user memory limit on the server to be exceeded and the Rails process that was handling that request was killed.

This happens even more frequently if you have more than one Rails application hosted from the same account.

To view the logs: Make sure your user is an SFTP or Shell user. Visit the Enabling Shell Access article for instructions. Log into your server using your client. Visit the FTP article for details. Once logged in, you’ll see several files; in this example we’re in the exampleuser’s directory noted by the ‘Remote site:’ field which shows /home/exampleuser: Click into the /logs https://help.dreamhost.com/hc/en-us/articles/216512197-Viewing-your-error-log-via-SFTP directory.

I've tried looking inside ./log in the rails application directory and there is nothing in any of the log files there. I've also tried looking at the web server logs themselves, and the access.log file dreamhost rails error shows an access to / and a request for the favicon, but nothing else, and the error.log is completely blank.

Dreamhost currently has Rails 2.2.2 installed.

Check the gem list in your environment.rb config file and ensure all gems are installed. You can also ssh into your application and run rake gems. rake gems RAILS_ENV=production You may want to freeze the gems if Dreamhost does not allow you to install them. rake rails:freeze:gems share|improve this answer answered Aug 5 '09 at 20:48 ryanb 13.6k23741 $ rake gems (in /mnt/local/home/collimarco/foto-fiori.com) - [I] mysql - [I] mini_exiftool I = Installed –collimarco Aug 5 '09 at 21:06 Can you run "script/console production"
