Hi All,
Wondering if anybody has seen this issue. I have a rails 3.2 app I am
trying to host on dreamhost. I am using FastCGI. When I attempt to
access the site, I get the "Rails application failed to start
properly"
error. I''ve determined that the ruby binary is crashing, and it is
producing a core file in the public directory of my app. I''ve also
determined that the crash is happening when the following line in the
application.rb file is executed:
Bundler.require(*Rails.groups(:assets => %w(development test)))
I have precompiled my assets. I''ve also tried without precompiling
assets and using the alternate line in application.rb for lazy
compilation of assets:
Bundler.require(:default, :assets, Rails.env)
I get the same result either way. Note that I''ve put logging into
application.rb to determine on which line the crash is happening. I get
the log message from immediately before the lines shown above, but I
don''t get the log message that immediately follows them.
Below is a backtrace from the core file, along with my .htaccess,
dispatch.fcgi, and config/application.rb files. Been fighting with this
since yesterday with no luck. Anybody have a clue as to what could be
wrong? Thanks for any help.
backtrace of ruby binary from gdb:
