Our pipeline, which has been running fine for a few months, threw the following error today. It looks like the worker pool was unable to be torn down after the pipeline finished:
Aug 31, 2015, 4:35:55 AM (95577a18aba47708): Workflow failed. Causes: (df2004d5f7046091): Step teardown_resource_global_gce_worker_pool2: Resource worker_pool_resource failed to shut down
Job_ID: 2015-08-30_11_01_50-8584391373463411570
Is this a known issue?
