Hi,

After enable Persistent Queues & Dead Letter Queues, the log file in dead\_letter\_queue directory is  
continue to create (2 new log files every minute).

And the content of all logs in dead\_letter\_queue directory is 1.  
[root@localhost main]# cat 1.log  
1[root@localhost main]#

What does this mean?
