Absence of deadlocks

Deadlocks arise due to a wrong combination of gateways and block the further process procedure. A process with a deadlock is not executable.

Deadlocks are blockages in the process model that occur when gateways are used incorrectly. Deadlocks occur when an exclusive gateway is combined with a parallel gateway for splitting and merging a process flow. They may also arise when intermediate events or multiple exclusive start events are added.

If you receive this error, double-check all gateways and intermediate events, as well as check for instances of multiple exclusive start events.
