HornetQ OutOfMemory与大杂志一起创业

使用:HornetQ 2.0.0.CR2独立/非群集服务器的默认配置.

当我尝试使用大日志(> 1Gb)启动服务器时,我得到了一个OutOfMemory异常:

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

当消费者停止处理消息并且我需要重新启动服务器时,这可能发生在现实生活中.

这有什么解决方法吗？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.

该寻呼它不是在默认配置中启用了!

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

   
      
      
         jms.queue.DLQ
         jms.queue.ExpiryQueue
         0
         10485760
         10

         
         104857600
         PAGE

      
   

现在可以有大量的队列等待处理.
