Hi,

We are facing an issue when the client application is pointing to our Jboss Dev environment. Client application makes call to backend service(deployed on jboss) for the purpose of caching templates at their end. The templates are 233 in number. So, backend api is called through ejb lookup for 233 iterations. The response is send back to client correctly for first four iterations and for the fifth iteration an exception is thrown.

We have checked that this is not data issue as we have removed the 5th element and  in that case it fails for next iteration.
