origin: error: build error: Failed to push image: unauthorized: authentication required

[provide a description of the issue]

oc start-build fails reporting

error: build error: Failed to push image: unauthorized: authentication required

However from the logs (–build-loglevel=5) it shows the following :

Version

[provide output of the openshift version or oc version command]

1.4.0-rc1 build from release-1.4 branch

oc v1.4.0-rc1+b4e0954 kubernetes v1.4.0+776c994 features: Basic-Auth GSSAPI Kerberos SPNEGO

Server https://master.ns.com.au:8443 openshift v1.4.0-rc1+9143f7b-65 kubernetes v1.4.0+776c994

Steps To Reproduce

Not easily reproducable as it doesn’t happen always.

If it happens, it usually self corrects after a few retries at the build.

Sometimes I try scaling the registry to 0 then back to 1 and that usualy fixes it.

Additional Information

oc adm diagnostics contains the following log entry :
