Failure to stop older versions of services

[tonglil]

In several GAE flex deployments, passing the additional flag --stop-previous-version has failed to turn off/scale down previous versions to 0.

This can result in developers being charged for idle instances in the project.

This error does not happen every time, maybe around 1 in 5-10 times.

• Deploying with stopPreviousVersion doesn't stop the previous version GoogleCloudPlatform/app-gradle-plugin#107

Perhaps the SDK should be updated?

We still see this behavior, were you able to find a reliable workaround?
