Kgio / unicorn not working

Question

I have a problem with unicorn / kg / rails. When I start the unicorn server with nginx and try to access the website through the web interface, I get the following error in unicorn.stderr.log

unicorn worker[1] -c config/unicorn.rb -E production -D: symbol lookup error: /var/www/project/shared/bundle/ruby/1.9.1/gems/kgio-2.7.4/lib/kgio_ext.so: undefined symbol: rb_thread_io_blocking_region E, [2012-07-30T13:43:46.580856 #17326] ERROR -- : reaped #<Process::Status: pid 3863 exit 127> worker=1 

Can someone help me?

Feel free to ask for any information.

Answer 1

Have you tried using unicorn_rails to run it?

There may be a problem with running this directly through Rack, what will happen, what happens when you type

 unicorn blah blah blah 

instead

 unicorn_rails blah blah blah 

I remember that this is the problem of one of our old unicorn apps. See Using the Unicorn Link for more information. See the Usage section.
