问题
I am new to ESB and am struggling to get it going. Would appreciate if someone can point me in the right direct to resolve this issue.
My Environment: OS: Ubuntu 12.04 (64bit) JDK: 1.7.0_51 (64bit) Fuse: JBoss Fuse 6.0
I am getting the following exception:

**The log file has this message which keeps repeating:**
Mar 20, 2014 10:51:20 PM org.apache.karaf.main.SimpleFileLock lock
INFO: locking
Mar 20, 2014 10:51:21 PM org.apache.karaf.main.SimpleFileLock lock
INFO: locking
Mar 20, 2014 10:51:22 PM org.apache.karaf.main.SimpleFileLock lock
INFO: locking
Appreciate any help that I can get. Many thanks in advance.

This happens when org.apache.karaf.main.SimpleFileLock is used to implement a simple master-slave failover deployment. More details can be found here.
If an already another FUSE ESB instance is running, then the second started instance is waiting until the first process is stopped. If you stop the first instance, the second instance will start and get the lock and the log entries will disappear.
Master and slave instance must refer to the same lock file in the file system. If this is not possible as master and slave are on different hosts, then org.apache.karaf.main.DefaultJDBCLock can be used.
