You have two options available for controlling your render job once it's been submitted to the render farm: Pause and Abort.
Click on your render job's name in the Render Rocket Dashboard (or Mission History) to view your job's details. If your job is running, you'll see the two controls as pictured below.
When you PAUSE your render job, the network will finish rendering any frames that have already begun rendering. You will continue to be charged for these running frames. As an example, if you currently have ten frames running and they each take one hour to complete, they will continue to render as normal if you click Pause.
Pausing only stops new frames from rendering. No new frames will be picked up until you RESUME the mission.
The Artist Care support team will not resume any job for you unless you specifically ask us to do so. However, if Artist Care notices a job that has been Paused for an extended period of time, we will try to contact you by email to notify you. If we do not receive a reply within approximately 24 hours, the paused render job will be aborted and any resulting charges from frames that have completed before the job was paused will be applied to your account.
Abort will stop all running frames, whether they have finished or not. Any completed frames will then be packaged. Your account will then be charged for any render time usage up to that point (including for the frames that were aborted mid-render).
When you click "Abort", you will be presented with a confirmation dialogue, as seen below. Aborted jobs cannot be resumed by the user.
To summarize, Pause will stop any new frames from rendering. Any currently-rendering frames will continue to render (this can generate expensive charges if the frames are "stuck" or have long render times). Abort will immediately stop all rendering. If you suspect an error with your render job, we advise that you Pause your job until you determine for sure that you are unhappy with how the job is progressing. Then, Abort your job as soon as possible to prevent any further charges.
