We had an issue with our Web dispatcher and most of the messages failed in the step "Receiver Grouping" with the error "HTTP_CLIENT_RECEIVE_FAILED" when calling the mapping runtime.
After sometime we also noticed the queues failing with the error "CLient receive failed:Queues stopped".
I am just wondering what the role of the web dispatcher could be in calling the mapping runtime.Can somebody please explain this to me ?
When a message is already being processed on an instance on the Int. Engine, the IE will call the JAVA stack on the same instance(if I am not wrong) then how can the error occur if the Web dispatcher is down.Moreover, in our visual admin properties we have checked the JCA Adapter settings and it is calling its "LOCALHOST" always.
Please explain me in detail the mapping runtime step.
