我是ESB的新手，我正在努力实现这一目标。如果有人可以直接指出我来解决这个问题，我将不胜感激。
我的环境： 操作系统：Ubuntu 12.04（64位） JDK：1.7.0_51（64位） 保险丝：JBoss Fuse 6.0
我收到以下异常：

**The log file has this message which keeps repeating:**

感谢我能得到的任何帮助。非常感谢提前。

当org.apache.karaf.main.SimpleFileLock用于实现简单的主从故障转移部署时，会发生这种情况。可以找到更多详细信息here。
如果另一个FUSE ESB实例正在运行，则第二个已启动的实例正在等待，直到第一个进程停止。如果停止第一个实例，则第二个实例将启动并获取锁定，日志条目将消失。
主从实例必须引用文件系统中的同一个锁文件。如果由于主服务器和从服务器位于不同的主机上而无法实现，则可以使用org.apache.karaf.main.DefaultJDBCLock。
