Javaハングインとcentos6でのクラッシュ
VPSでJavaプログラムを実行する際に問題が発生しました。
症状：
- 起動して少しの間実行した後、CPUを使用せずにそのままハングします。通常、割り当てられるメモリの量は異なります。
- Javaとjavacの両方で開始すると、エラーが表示されます
- 実際に実行されます。非常にまれに発生し、通常はハングします
- ログファイルで致命的なエラーが検出されました

非常に簡単に推測すると、「JavaThread「SIGINTハンドラ」デーモン」は、スレッド/プロセス/ RAM/CPU/iノードなどのリソース制限を超えたために、ISPホストがプロセスを強制終了している可能性があることを示唆しています。
OOMキラーもありますが、それは/var/log/messagesファイルに記録されると思います
