To stop a deployment manually, from the Details tab click Halt Deployments.
The Details tab also contains a Critical Reset button, which you can use to delete the last deployment that was made to the given target (the current deployment). The operation clears the deployment state one by one from each agent, deleting the deployment data directories from the ATG Content Administration server as well as from the target. All agents are reset to IDLE. Typically you use the Critical Reset operation only in situations where errors occurred that are irrecoverable by other means (stopping the deployment, fixing the error, and either resuming or rolling back the deployment).
