I use jboss-6.0.0.M2 as my jms server。when I install jboss in Debian，I can send and recieve jms message 。but when I install jboss in redhat，nothing happens after I send jms message to jboss：

producer.send(txtMsg);

As I checked the code，I find out when I use this method

producer.setTimeToLive(60000l);

jms message will not send to jboss.When I delete this code, Jboss can recieve the message

Does anyone know this problem ， thank you
