Microsoft pushed SharePoint 2014 August 2014 patches through WSUS. After install these patches on servers within farm, you will need to rerun the wizard of SharePoint to upgrade all instances.
One error on my scenario is related to Microsoft Server Proof. Wizard reports patches for this component are missing on all servers except the server which running the wizard.
That’s the problem related to configuration database. To fix this, you just need to run Get-SPProduct -local on all servers.
