Saving endpoint to store fails in windows under concurrent load #1950
Description
We are trying to create a lot of parallel containers on windows. As part of the workflow multiple endpoints are being created and saved simultaneously. When this happens some container creation fails as docker is not able to save the endpoint to store:
time="2017-09-12T19:53:30.792343000-07:00" level=debug msg="FIXME: Got an API for which error does not match any expected type!!!: failed to create endpoint eager_newton on network nat: failed to save endpoint 53944a9 to store: failed to update store for object type *windows.hnsEndpoint: open C:\docker/network/files/local-kv.db.lock: The process cannot access the file cause it is being used by another process." error_type=types.internal module=api
I am waiting for a repro machine to track this. Probably only happens on slow machines but creating an issue for tracking. This is also causing some noise in docker CI aswell.
