milkode実行中にGroonga::ResourceDeadlockAvoidedのエラーが生じる

[さがさん]

前提・実現したいこと

milkodeを利用して、複数のgitレポジトリを登録、コードを検索できるようにしたいと思っています。

行っている処理は以下のとおりです。

• git cloneする
• git cloneしたディレクトリをmilkodeへ登録する
• 上記をgithubへ登録しているレポジトリ数繰り返す

途中まで問題なく進んでいましたが、数百回目の繰り返しの実行中に以下のエラーメッセージが発生しました。

何か確認すべき点などがございましたら、ご教授いただけますと幸いです。

不足の情報などございましたらご指摘いただけますでしょうか。

生じたエラー

milk add をする際に、下記のように

試したこと

• milkodeのセットアップをやりなおし、再実行した。(ディレクトリ削除し、milk initする）
  →　同じエラーが生じる
• エラーが生じた後に、手動によりmilk update -v hogehogeを行った。
  →　処理が進まない

$ milk add hogehoge [error] package named 'hogehoge' already exist. $ milk update hogehoge package : hogehoge 処理が止まる

使用バージョン

CentOS:6.7
milkode:1.8.9
ruby:2.2.5
