ABSTRACT
Current Internet service architectures lack support for salvaging stateful client sessions when the underlying operating system fails due to hangs, crashes, deadlocks, or panics. The Backdoors (BD) system is designed to detect such failures and recover service sessions in clusters of Internet servers by extracting lightweight state associated with client service sessions from server memory. The BD architecture combines hardware and software mechanisms to enable accurate monitoring and remote healing actions, even in the presence of failures that render a system unavailable.
