appEngine stopping automatically earlier than configured

[Sami Lahti]

See image attached. Can anyone explain why AppEngine stops sometimes within one minute of its starts thought it is configured to stop in one hour? And does that repeatably.

Hi,

Generally speaking the app engine instances can be shutdown for planned and unplanned reasons shown here [1].

There are some planned shutdowns on the instances with automatic_scaling to update the libraries in the host machines and in the runtime environments, the instances are shut down one by one and restarted with the new patch.

However, App Engine tries to run indefinitely the basic_scaling and manual_scaling options [2]

If you need more information about this issue I suggest opening a GCP support ticket to keep sensitive information private.
