axis2: Parser already accessed!

Sun, 22 Jul 2007 19:34:22 -0700 


HI,
We have an intermittent problem when sending a large XML message which has an encoded PDF attachment with base64. 
We are using a generated stub from xmlbean for sending the message.
We are using Axis2 1.2 & xmlbeans 2.2, Axiom 2.4, Tomat 5.5 & java 5.
Our assumption is that this is something to do with the cache and getting the parser but are a little confused about why this exception is being thrown. (especially only sometimes) 

Are there any resource that we should clean up before sending?

Here is the exception trail:
