###当然のエラー
普段capistrano + nginx + unicorn でデプロイを行っているのですが、以下のエラーが出て対処に困っています。

###該当のソースコード
正直、どこが悪いのか見当もつかないのでご指摘していただけると嬉しいです。

スマホからなのでぱっと見なのですが、unicorn再起動時にプロセスを止めようとしてるがそもそもunicornが走ってないので止まってるように見えます。
解決策としてはunicornの再起動タスクをstopとstartの２つに分割して、startのみ走らせれば良いかと思います。うまくいったら再起動タスクに戻す感じですね。
あとはサーバで手動でunicorn走らせて、デプロイしてみるのも一つですね。

回答ありがとうございます。
まさにおっしゃる通りで、サーバーを再起動させたのちに時間をおいてunicorn スタートさせると上手くいきました。ありがとうございました。
