凄い嵌った・・・
今日1日は、これで費やしてしまった・・・・

だって、C3P0の日本語サイト少ないし、しかもみんなハイバネートだし・・・

単体で、C3P0を使っている人は少ないようで、僕が特殊？

まぁ、そんな訳でエラーログを

悪さをしていたのは、spring のBeanNameAutoProxyCreator

もっというとサーバの設定がちゃんとされてないじゃん！！
WEB1台、DBを2台使って、一つのDBに接続できず・・・

トランザクションを実行するとプールが消滅してる！？って思い、凄い嵌った・・・

iptables やるなら、ちゃんとやってくれよ・・・

MYSQL でアクセスプログラムが、「Lost connection to MySQL server during query」　というエラーで落ちた

とりあえず、

Select Count(id) From table

とやっても、同じエラー

Select * From table limit 1

うん、表示される

やっぱ、DBサーバがショボイから落ちたのか

table には、28万件以上のデータがはいってるのに、メモリ386Mで、よく動いているよ、このテストサーバは

落ちても許そうｗ

AddType application/x-mpeg .amc

ないと、「ダウンロードデータが正しくありません」と返される
