XML documet structures Error

Periodically we experience an “XML document structures must start and end within the same entity” fault. This causes tags to go stale, and to get rid of the fault requires a gateway restart. Any Ideas?

That error message means that the Gateway experienced an unexpected exception while sending a response to the client - hence the XML error message in the Client (the response was garbled).

The Gateway logs will probably shed some light on the true cause of the problem.
