A dataflow program defining actors that pass tokens from one to another via connections is processed by causing one or more processors to access and execute instructions of the dataflow program. Execution of the dataflow program generates events (e.g., token production/consumption, actor state after actor action firing). For each generated event, processing evaluates whether there exists a sequence of events that matches a breakpoint condition, and if such a sequence exists then execution of the dataflow program is halted. The breakpoint condition is at least partially based on an extended history of related events, wherein two events are related to one another if they pertain to a same connection or if they pertain to a same actor state, and wherein the extended history comprises at least two related events.
