Securing Remote Desktop for Windows XP

• Railsアプリを1日放置しているとMongrelが刺さる問題
• Rails + MySQL (+ Mongrel?) でDB接続の通信が無い状態が続くとデッドロックする。
• TCPSocket#flushでスレッドが停止する現象について

以下のようにいずれかを避けることで問題を回避することができるはずである。

1. MySQLのクライアントライブラリを使用したバイナリ版のドライバをインストールする
   sudo gem install mysql
   gem install mysql -- --with-mysql-dir=/usr/local/mysql
   
2. Mongrelの使用をやめ、FastCGIなどにする
3. MySQLのコネクションがタイムアウトしないようcron等で定期的にアクセスする

Rails: MySql lost connection error with Mongrel

Mongrel stops responding a few times per days. Restarting Mongrel helps.

Q: Mongrel stops working if it's left alone for a long time.

If you find that Mongrel stops working after a long idle time and you're using MySQL then you're hitting a bug in the MySQL driver that doesn't properly timeout connections. What happens is the MySQL server side of the connection times out and closes, but the MySQL client doesn't detect this and just sits there.

What you have to do is set:

ActiveRecord::Base.verification_timeout = 14400

Or to any value that is lower than the MySQL server's interactive_timeout setting. This will make sure that ActiveRecord checks the connection often enough to reset the connection.
