この問題を解決する方法についてアドバイスをいただければ幸いです。
jetty websocket (9.2.6.v20141205) クライアントを使用して、apache2 proxy_wstunnel 経由で tomcat7 websocket サーバーに接続しています。
次のエラーが断続的に発生します。

apache2 proxy_wstunnel を削除すると、エラーはなくなります。また、ngrep ログで apache が 500 エラーを出していることに気付きましたが、LogLevel デバッグをオンにしても、関連するログが表示されません。これには私の時間が数時間かかりました。Tomcat ログにもエラーはありません。
wstunnelを使い続けたいです。おそらく、これは桟橋のバグまたは apache のバグですか?
ngrep ログは次のとおりです。
