Axis response ends in 0???

I"m using Axis 2 1.6.1, we made beans, did java2wsdl, and axis handles everything for us. 

We had an error report that occasionally clients are failing because an extra 0 is sent after the response.

I looked in our samples, and they show some extra hex codes before and after the XML (though Im not sure if this is due to the capture not being prescise?)

Here are my captured requests and responses from the generated Axis client and server.  Notice the numbers at the beginning and end.  Has anyone ever heard of this and know how to get rid of it?  Some clients complain about it sometimes.
