Do we know which test is failing? The last messages in the log are from , but I don't actually see a test failure message printed, and I can't recreate any failures.

The "Unable to authenticate the request due to an error: Token has been invalidated" messages are expected since the test exercises attempting to use invalid tokens () Also, the "Stop requested" messages indicate that particular test completed and invoked the deferred stopFunc, which shuts down the controllers and closes the test server
Here is the failing test: --- FAIL: TestPersistentVolumeClaimBinder (3.45s) Expected claim to be bound: &{TypeMeta:{Kind: APIVersion:} ObjectMeta:{Name:claim02 GenerateName: Namespace:default SelfLink:/api/v1beta1/persistentVolumeClaims/claim02?namespace=default UID:-f9c3-11e4-96ec- ResourceVersion:172 CreationTimestamp:2015-05-13 22:54:47 +0000 UTC DeletionTimestamp:<nilLabels:map[] Annotations:map[]} Spec:{AccessModes:[ReadOnlyMany ReadWriteOnce ReadWriteMany] Resources:{Limits:map[] Requests:map[storage:{Amount: Format:BinarySI}]} VolumeName:} Status:{Phase:Pending AccessModes:[] Capacity:map[]}}
you aware of the issue with TestPersistentVolumeClaimBinder?
I ran into above issue a lot.
Sorry, hadn't seen this sooner. Lost in the flurry of email traffic. I am looking into it now.
I cannot reproduce on F20, Go 1.3.1 I'll try 1.4 next. Any other info would be appreciated.
Here is the output of docker version from my desktop. Client version: 1.6.2 Client API version: 1.18 Go version (client): go1.4.2 Git commit (client): OS/Arch (client): linux/amd64 Server version: 1.6.2 Server API version: 1.18 Go version (server): go1.4.2 Git commit (server): OS/Arch (server): linux/amd64 I started to run into this issue two days ago, and just ran into it half hour ago right after I sync-ed to HEAD again. Any more information you need here?
Thanks :)
I cannot reproduce this on F20, Go 1.4.2 Any runtime settings I might be missing? I see hack/test- is set to "-race" .
