Hello all. I''ve run into a strange problem with Unicorn, and Google
couldn''t help me out. Basically, I''m going to switch from
Passenger to
Unicorn for the next release of my Rails app. I installed it on my
local machine, and it ran great. But then, as I was building my new
server to deploy on, I ran into a snag.
When I run ''unicorn_rails'', I got a strange error.
Here''s the output
of ''unicorn_rails -d'' :
$ unicorn_rails -d
{:daemonize=>false,
:unicorn_options=>{:listeners=>[]},
:app=>

And then it just repeats.
I''m using ree both locally and on the server (as you can see), but
I''m
using it through rvm locally.
Any idea what this might be?
Thanks,
Steve

Unicorn depends on Rack and since Unicorn is always loaded before Rails is, the Unicorn dependency will always load the newest version of Rack on the system. Uninstalling Rack 1.1.0 for now should fix things, just keep Rack 1.0.1 installed). I''ll add this to the FAQ for now, not sure if there''s a sane solution for it... -- Eric Wong

I went nuts on this today. It''s Rack 1.1 that is messing with you and stupid stupid rails that, in boot.rb has this: rescue Gem::LoadError => load_error $stderr.puts %(Missing the Rails #{version} gem. Please `gem install -v=#{version} rails`... ... end Rails assumes the only reason for failure is a missing Rails install, but if you throw in a #{load_error.inspect} in there the Rack issue shows up loud and clear... Always always include the actual error in a log statement when you rescue! :)> Exception `Errno::EAGAIN'' at > /opt/ruby-enterprise-1.8.7-2009.10/lib/ruby/gems/1.8/gems/unicorn-0.96.0/lib/unicorn.rb:436 > - Resource temporarily unavailable > I, [2010-01-19T21:25:09.918670 #30184] INFO -- : reaped > #<Process::Status: pid=30185,exited(1)> worker=0 > Exception `Errno::ECHILD'' at > /opt/ruby-enterprise-1.8.7-2009.10/lib/ruby/gems/1.8/gems/unicorn-0.96.0/lib/unicorn.rb:454 > - No child processes > > And then it just repeats. > > I''m using ree both locally and on the server (as you can see), but I''m > using it through rvm locally. > > Any idea what this might be? > > Thanks, > Steve > _______________________________________________ > Unicorn mailing list - mongrel-unicorn at rubyforge.org > http://rubyforge.org/mailman/listinfo/mongrel-unicorn > Do not quote signatures (like this one) or top post when replying
