If you’ve the same kind of problem, with your god logging showing “kill: 1: No such process“, then change the exists? method in /usr/local/lib/ruby/gems/1.8/gems/god-0.5.0/lib/god/system/process.rb file, gem path might not be the same on your system.

# Return true if this process is running, false otherwise
def exists?
    # system("kill -0 #{@pid} &> /dev/null")
    ps_int('rss') != 0
end

Here is our configuration if some people can find where this line is causing problem: Ubuntu Gutsy, Ruby 1.8.6, God 0.5
