ACTIVEMQ Channel was inactive for too (>30000)long

警告问题

生产服务器上，MQ Produce和consumer端同时报如下错误，导致不能正常工作。

Transport Connection to: tcp://0.0.0.0:54301 failed: java.io.EOFException | org.apache.activemq.broker.TransportConnection.Transport |

官网解释如下：

2012-06-26 17:13:55,712 | DEBUG | 30000 ms elapsed since last read check. | org.apache.activemq.transport.AbstractInactivityMonitor | InactivityMonitor ReadCheck

Setting transport.useInactivityMonitor=false will disable the InactivityMonitor. Configuring wireFormat.maxInactivityDuration=0 will achieve the same result.

解决方法:

　查看配置,在activemq的 conf/activemq.xml 里设置了InactivityMonitor的连接超时时间导致,如:
通过设置连接URL的属性:　tcp:/ / 0.0.0.0:61616 ? wireFormat.maxInactivityDuration = 30000,表示如果30秒没有数据被读取,接InactivityMonitor假定有一个连接的问题。 InactivityMonitor抛出一个InactivityIOException和关闭相关的转换连接.
解决方案：wireFormat.maxInactivityDuration=0，禁用InactivityMonitor　

uri=”tcp://0.0.0.0:61616?wireFormat.maxInactivityDuration=30000”

　修改为

uri=”tcp://0.0.0.0:61616?wireFormat.maxInactivityDuration=0”
