I wrote this quick test script:
---8<---
require 'ruote'
#ruote = Ruote::Dashboard.new(Ruote::Worker.new(Ruote::HashStorage.new))
ruote = Ruote::Engine.new(Ruote::Worker.new(Ruote::HashStorage.new))
ruote.noisy = true
FileUtils.mkdir('subprocesses') rescue nil
File.open('subprocesses/send_mail', 'wb') do |f|
f.puts(%{
#Ruote.define 'send_mail' do
Ruote.process_definition 'send_mail' do
echo '** sent mail'
end
})
end
wfid = ruote.launch(Ruote.define do
echo '* in'
subprocess :ref => 'subprocesses/send_mail'
echo '* out'
end)
ruote.wait_for(wfid)
--->8---
and it worked fine with ruote 2.2.0 (gem) and ruote 2.2.1 (master).

I have the impression that your flow is stuck in an error.
Try to run with engine.noisy = true and it will log each workflow
operation to the STDOUT, including the detailed error if any.
If you can't do that you could do something like:
---8<---
p engine.process(wfid)
--->8---
And it will print the complete state of your workflow instance.
If you're using ruote-kit, look at /_ruote/errors/ (IIRC).
For more information, look at:

I hope this will help, cheers,
