うるう秒でいろいろ朝から面倒だった件
**[追記 20120702] dateコマンド修正しました** いつか役に立つかもしれないので。。。。 [2012-07-02 うるう秒のあとにMySQLなどのCPU使用率が高騰する件について](http://d.hatena.ne.jp/sh2/20120702)のエントリーで、 1. NTPを動かしていてうるう秒の挿入がある 1. MySQL 5.5を使っている 場合にCPU使用率が上がる可能性があるとあったので、調べてみたらやっぱりCPU使用率が上がってました。。。 あと、javaが暴走していると聞いたので、jenkinsがやばいかもと思ったら、やっぱりダメでした。。。 ## MySQLのCPU使用率の上昇の対応 sshはできる状態でした。 LAは少し高いくらいでした。 * MySQLのバージョン
