To hard terminate a runaway process when graceful shutdown fails, you execute an immediate kill command. This ensures instant shutdown to prevent cascading failures and data loss in emergency containment scenarios.

A graceful shutdown attempts to safely end a process, while a hard process kill forces immediate termination. Hard termination is applicable when graceful shutdown fails or during a security breach requiring instant containment.

You should perform an emergency shutdown of a misbehaving process when it becomes a runaway, when graceful shutdown is not viable, or during a security breach requiring instant termination to prevent cascading failures.

After terminating a rogue process, you must perform a blast-radius assessment and document the kill decision. This provides clear post-termination guidance and generates an incident seed for further analysis.

Using a hard kill to stop a runaway process carries a risk of data loss because it forces immediate shutdown. However, it is necessary to prevent larger cascading failures when graceful shutdown is not an option.
