これはtomcat 7.0.xでメモリリークを引き起こす可能性が非常に高い

Question

"これはメモリリークを引き起こす可能性が非常に高い"エラーです。一度エラーが出たら、activeMQに接続できませんでした。私からのActiveMQに接続しようとしています

<bean id="activemq" class="org.apache.activemq.camel.component.ActiveMQComponent">  
    <property name="brokerURL" value="${url}" /> 
</bean> 

$ {URL}が

tcp://activeMQhost.localnet/192.168.0.15:61616?keepAlive=true&trace=true 

に設定されている

春豆：私たちは、recently.Hereがトレースされ、このエラーに気づきましたあるマシンから別のマシンへたとえば、machine1とactiveMQ running activeMQhostで実行されているWebアプリケーションです。いくつかの時間、スレッドは何らかの理由で閉じることができませんでした。あなたは、トレースの終わりに接続URLを見つけることができます。

tcp://activeMQhost.localnet/192.168.0.15:61616 

Answer 1

あなたの代わりにフェイルオーバー・トランスポートを使用して検討するかもしれない...その、より堅牢であっても、単一のブローカー接続

http://activemq.apache.org/failover-transport-reference.html

Answer 2

のためにあなたをあなたの接続ファクトリBean（通常はActiveMQでは 'stop'、ラクダのバージョンについてはわからない）にdestory-methodを指定してみてください。

<bean id="..." class="..." destroy-method="stop"> 
    ... 
</bean>
