Maintaining state information in a multi-component, event-driven state machine

A method, apparatus and computer program product that allows for maintaining correct states of all sub-components in a state machine, even as sub-components leave the state machine and later rejoin in some previous state. Preferably, this is achieved without requiring the system to remember the states of all sub-components or a log of every event that was fed into the state machine. Thus, the technique does not require any knowledge of the previous state of the sub-components nor the need to preserve a complete log of events that were fed into the state machine. The state machine may be used to enhance the operation of a technological process, such as a workload management environment.
