Overview
An active build is a build the is currently executing. There is at most one active build per project, as governed by the build queue.
Terminating Builds
An active build may be terminating by clicking on the "cancel" link in the appropriate row of the "active builds" table. This will move the build into the terminating state and, if there is a recipe being processed for the build, a request to terminate the recipe will be sent to the recipe processor. The recipe processor will terminate the build at the next available opportunity (potentially by killing processes launched by the current command), and the build will complete in the error state. Refer to the Build States page for details.
