Unicorn error

Are permissions set correctly in all of your application folders?

/usr/local/rvm/gems/ruby-1.8.7-p302 at project/gems/unicorn-
3.5.0/lib/unicorn/util.rb:19:in `chown': Operation not permitted -
/home/user/project/shared/log/unicorn.stderr.log (Errno::EPERM)
       from /usr/local/rvm/gems/ruby-1.8.7-p302 at project/gems/unicorn-

Looks to me you may need to do a chown -r app_user /app_directory/
where app_user is the user unicorn is running on. Does unicorn work
with sudo?
