GetSpec() can be called concurrently in manager/container.go.updateSpec() results into a concurrent map access on the labels map because we're directly updating the map inside GetSpec(). The labels map from the container handler is not a copy of the map itself, just a reference, that's why we're getting the concurrent map access. Fix this by moving the label update with restartcount to the handler's initialization method which is not called concurrently. Signed-off-by: Antonio Murdaca <runcom@redhat.com>
