Hey guys, I have an application which uses MDB to drive an async process flow. But in running the app, there are numerous occasions when sending a message to the Queue fails. Here are a couple of the exceptions I'm getting:

Does anybody know why this is happening? On the good side, I'm able to guarantee all messages getting sent by putting a resend in the catch of the JMSException on a sent message, but this doesn't seem like the right approach for this issue...

Thanks!
