Zusammenfassung:Mechanisms are provided, in a data processing system, for generating a snapshot of a remote direct memory access (RDMA) resource. The mechanisms receive, from an Input/Output (IO) adapter associated with the data processing system, an error event notification and store, in response to the error event notification, a snapshot of a RDMA resource associated with the error event notification. The mechanisms tear down the RDMA resource in response to the error even notification and free memory associated with the RDMA resource in response to tearing down the RDMA resource. The snapshot stores contents of the RDMA resource.
