Tomcat7がアプリのデプロイでハングする

Ubuntu 14.04のTomcat 7で非常に奇妙な動作をしています。

新しいVPSを作成し、default-jdkとその他の単純なものをインストールしました。 Tomcat 7をダウンロードして解凍しました。[myIP]:8080で実行できることを確認し、Tomcatのインデックスページを確認しました。

VPSを再起動したら、Tomcatを再起動しましたが、[myIP]:8080に応答がありません。エラーすらありません。ログを確認したところ、Tomcatが最初のWebアプリケーションでの展開の状態でハングしていることがわかりました。

74行目までは、これは通常のサーバー起動です。すべての標準Webアプリケーションがデプロイされました（行48〜68）が、その後ハングしました。そこで、サーバーを停止してシステムを再起動しました。 Tomcatを再び開始し、奇跡が始まります。次のセッションは89〜136行目にあり、Server startup in xxxx msのエントリがないことがわかります。

展開中にハングアップするだけで、この状況は常に繰り返されます。何が原因でしょうか？私はこの問題に苦労して何時間も費やしてきましたが、気が狂ってどこにも行きません。

考えられる問題は、エントロピーの増加を待つTomcatです。 jstackを使用していくつかのスレッドダンプを取得し、誰が何を待っているかを確認します。

Tomcat 7+は、SecureRandomクラスに大きく依存して、セッションIDなどにランダムな値を提供します。 JREによっては、SecureRandomの初期化に使用されるエントロピーソースのエントロピーが不足している場合、起動時に遅延が発生する可能性があります。

問題がエントロピーである場合、次のシステムプロパティを設定することにより、ノンブロッキングエントロピーソースを使用するようにJREを設定する方法があります。

-Djava.security.egd=file:/dev/./urandom
