+- `killBehavior` (optional) - Dictates if your worker will be deleted in case a task is active on it.
+ **KillBehaviors.SOFT**: If `currentTime - lastActiveTime` is greater than `maxInactiveTime` but a task is still executing or queued, then the worker **won't** be deleted.
+ **KillBehaviors.HARD**: If `currentTime - lastActiveTime` is greater than `maxInactiveTime` but a task is still executing or queued, then the worker will be deleted.
+ This option only apply to the newly created workers.
+ Default: `KillBehaviors.SOFT`
