Builder exits unexpectedly

[crawlik]

We downloaded /thoughtworks-cruisecontrol.rb-422b3ee from https://github.com/thoughtworks/cruisecontrol.rb/downloads. Got it installed and running but some projects exit unexpectedly. Here is log trace from builder.log.

[info]  [2012-01-19 23:06:08] Builder for project 'Z' exited

Looks like there an exception which is not handled by this code in script/builder. Guys any recommendations what to do about it?

begin
  project = load_project(project_path)
  startup(project)

  write_to_log_and_console "Builder for project '#{project.name}' started"
  puts "Logging to: #{File.expand_path(CRUISE_OPTIONS[:log_file_name])}"

  while (true) do
    catch(:reload_project) do
      project.scheduler.run
    end
    project = load_project(project_path)
    # this will cause the next call to scheduler to run the build immediately
    project.request_build rescue nil
  end
rescue Interrupt
  # this is okay, we're just control-c'ing the app
rescue Exception => e
  begin
    CruiseControl::Log.fatal(e)
  rescue => logging_error
    STDERR.puts e.message
    STDERR.puts e.backtrace.map { |line| "    #{line}" }
    STDERR.puts "Attempt to log the above error failed with this:"
    STDERR.puts logging_error.message
    STDERR.puts logging_error.backtrace
  end
  CRUISE_OPTIONS[:verbose] ? raise : exit(1)
ensure
  cleanup(project)
end

@crawlik - Which version of rails are you using? From a bit of research it seems that some older versions (2.3.x) may have a bug causing issues with STRERR stream writes in particular circumstances. I'm unable to find much in the way of compelling documentation on the specifics and/or practical fixes. If you are using an older version of rails I'd suggest upgrading if that's possible.

If that isn't a practical solution can you please post the specifics of your environment (ruby version/rails version/platform/anything else special you're doing).
