> There is a {{BackgroundPipelineCreator}} thread in SCM which runs in a fixed
> interval and tries to create pipelines. This BackgroundPipelineCreator uses
> {{IOException}} as exit criteria (no more pipelines can be created). In each
> run of BackgroundPipelineCreator we exit when we are not able to create any
> more pipelines, i.e. when we get IOException while trying to create the
> pipeline. This means that
> {{scm_pipeline_metrics_num_pipeline_creation_failed}} value will get
> incremented in each run of BackgroundPipelineCreator.
