Goal

Getting frequent weblogic.sca.api.ScaException: Invocation from SCA engine is invalid errors

A remote service reference is injected into a service and is used for invoking the remote service. We have 8 different server clusters, but seeing a "weblogic.sca.api.ScaException: Invocation from SCA engine is invalid." error on only 1 cluster. This is occuring on every alternate request and is causing major customer provisioning issues. When a request is sent again, the same cached remote reference is able to make the remote call.

Below is the exception trace, no other information is available. Nothing is prinred in soa server.out or log or diagnostic logs
