An inter-process communication (IPC) system, includes a first client engine, a first server engine, and a broker engine that is coupled to the first client engine. The broker engine initiates a first timer that is configured to reset when traffic is received from the first server engine while the first server engine is registered with the broker engine and coupled to the broker engine via a communication channel. The traffic that causes the first timer to reset includes at least one of: traffic generated by the first client engine to complete a request, and a first server-to-broker heartbeat message generated by the first server engine. The broker engine determines that the first timer has reached a predefined time amount, and in response, removes the registration of the first server engine and removes the communication channel between the broker engine and the first server engine.
