以前mroongaのインストール手順についてお世話になりました、 wakisukeこと宮脇です。 この度、リリースされたmroonga2.0.8にアップデートをしたのですが、 アップデート後、mroongaエンジンを使ったテーブルへインサートを行うと、 必ず以下のメッセージを出して、mysqlが再起動するという症状が起きています。 ERROR 2013 (HY000): Lost connection to MySQL server during query アップデートのミスかと思い、OS（Centos6.3）ごとクリーンインストールした のですが、 状況変わらずでした。 また、以前のデータベースでの問題ではなく、 現在ではmgoongaのユーザガイドに記載されている、基本的なインサート文でも 上記同様にmysqlの再起動が発生します http://mroonga.github.com/ja/docs/userguide/storage.html#how-to-use-full-text-search エラーログにも疑わしい記録がなく、 現在mroongaエンジンを使ったテーブルにはインサートが一切機能しない状況です。 （mroongaエンジンを使用していないテーブルへのインサートは可能です、その 他alterを使ったmroongaテーブルの作成は可能で す） 以上となります。 こちらで原因特定できず申し訳ありません。 何卒、よろしくお願い致しますm(_ _)m 以下にテーブル作成からインサートまでの実行文と、 エラーログの履歴を記載します ************************ SQL文 mysql> CREATE TABLE diaries (id INT PRIMARY KEY AUTO_INCREMENT, content VARCHAR(255), FULLTEXT INDEX (content)) ENGINE = mroonga DEFAULT CHARSET utf8; Query OK, 0 rows affected (0.30 sec) mysql> INSERT INTO diaries (content) VALUES ("明日の天気は晴れでしょう。"); ERROR 2013 (HY000): Lost connection to MySQL server during query mysql> INSERT INTO diaries (content) VALUES ("明日の天気は晴れでしょう。"); ERROR 2006 (HY000): MySQL server has gone away No connection.

It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail. key_buffer_size=8384512 read_buffer_size=131072 max_used_connections=1 max_threads=151 thread_count=1 connection_count=1 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 338324 K bytes of memory Hope that's ok; if not, decrease some variables in the equation.
