使用：HornetQ 2.0.0.CR2 独立/非集群服务器的默认配置。

当我尝试使用大日志（> 1Gb）启动服务器时，出现 OutOfMemory 异常：

当消费者停止处理消息并且我需要重新启动服务器时，这可能会在现实生活中发生。

有什么解决方法吗？或者我应该尝试修改哪些配置？

事实证明，完全避免这个问题很简单。

在默认配置中没有启用分页！

在 hornetq-configuration.xml 中添加这两行应该可以解决问题：

   <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>

现在可能会有大量队列等待处理。

从这里看来你的堆太小了。

如果垃圾收集花费的时间过多，并行收集器将抛出 OutOfMemoryError：如果垃圾收集花费的总时间超过 98%，而堆回收的不到 2%，则会抛出 OutOfMemoryError。此功能旨在防止应用程序长时间运行，同时由于堆太小而几乎没有进展或没有进展。如有必要，可以通过在命令行中添加选项 -XX:-UseGCOverheadLimit 来禁用此功能。

您是否尝试过修改 JVM 内存选项，-Xmx尤其是（可分配的最大内存）？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你的消息。

如果它是在开发者的，你可以通过删除你的HornetQ 工作目录（例如~/work/hornetq）来简单地删除你的队列。
