Mac OS X Lion で Ruby v1.8.7 と Daemons v1.1.8 を使用して、コンシューマー プロセスを作成し、デーモンとして実行しようとしています。
# config[:name] => 'idx_my_delete_consumer'
# config[:daemon] => {:multiple => false,
# :バックトレース => true,
# :dir_mode => :ノーマル,
# :log_dir => '/Users/pprakash/consumer.log',
# :モニター => true,
# :dir => '/Users/pprakash/pids'}
Daemons.run_proc(config[:name], config[:daemon]) do
消費者 = MyConsumer.new(config)
consumer.subscribe
終わり
ただし、開始せず、代わりに次のような長いトレースバックをスローします。

この問題の原因がわかりません。ディレクトリ名、ログファイル名はすべて有効です。これらの構成で MyConsumer のインスタンスを作成し、その #subscribe をスタンドアロン プログラム/コンソールから適切に実行できます。
