题

使用：HornetQ的2.0.0.CR2 默认配置为单机/非群集服务器。

当我试图启动一个大的期刊（> 1GB）的服务器，我得到了一个内存溢出异常：

[main] 12:59:43,505 INFO [org.hornetq.integration.bootstrap.HornetQBootstrapServer]  Starting HornetQ Server

这会发生在现实生活当消费者停止处理消息，我需要重新启动服务器。

有这个任何解决方法吗？或配置，我应该尝试修改？

有帮助吗？

解决方案

原来这是简单的，完全避免了这个问题。

的 寻呼 它不是在默认配置中启用了！

添加在hornetq-configuration.xml文件这2行应该做的伎俩：

   <address-settings>
      <!--default for catch all-->
      <address-setting match="#">
         <dead-letter-address>jms.queue.DLQ</dead-letter-address>
         <expiry-address>jms.queue.ExpiryQueue</expiry-address>
         <redelivery-delay>0</redelivery-delay>
         <page-size-bytes>10485760</page-size-bytes>
         <message-counter-history-day-limit>10</message-counter-history-day-limit>

         <!-- Add these 2 lines -->
         <max-size-bytes>104857600</max-size-bytes>
         <address-full-policy>PAGE</address-full-policy>

      </address-setting>
   </address-settings>

现在它可能有巨大的队列等待处理。

其他提示

从这里它出现在堆太小。

  

在平行集电极将引发   如果OutOfMemoryError错误太多时间   花在垃圾收集：如果   的总时间的98％以上是   花了垃圾收集和少   比堆的2％被回收，一个   OutOfMemoryError异常将被抛出。这个   功能旨在防止   从一个运行的应用程序   延长的时间周期，同时使   很少或根本没有进展，因为堆   太小。如果必要的话，这   特征可以通过添加被禁用   选项-XX：-UseGCOverheadLimit到   命令行。

您是否尝试过修改您的JVM内存选项，特别是-Xmx（最大内存分配）？我怀疑你需要增加你的JVM最大内存，给它足够的空间来处理邮件。

如果它是一个开发者，你可以简单地放下你的队列中删除您HornetQ的工作目录（例如〜/工作/ HornetQ的）。
