Hi,

I am using JBOSS 4.0.4 with Suse Linux 9 for my application. And i am getting following problem randomly while running my applicaton. In my application, we are using jboss-messaging-1.0.1.GA.

I don't know in which scenario JBOSS throw this exception.

Please let me know immediately since we are facing this issue in client place.
