[chef] Template being updated every chef run

[Alfredo Palhares < >]

Hello,

I have a simple template like this

template "/etc/nagios3/conf.d/pagerduty_nagios.cfg" do
  source "pagerduty_nagios.cfg.erb"
  owner "nagios"
  group "nagios"
  mode 00644
  variables(
    :pager => pagerduty["pager"]
  )
  notifies :restart, resources(:service => "nagios3")
end

What happens it that the template its updated every time chef-client runs, 
and nagios is restarted
wich is bad, silly and annoying.
Chef claims the content, user and group changed. But it doesn't. File 
checsum, user and group does
not change.
Here is the full chef-run[1]. User 104 is nagios user.

Help, because i am clueless why this happens
