We observed an issue on a test platform just upgraded in last 6.6 patch (6.6.0.10385).
The deployment counter on the 'Overall System Status' widget is not incremented when launching deployments.
The number stays at '0' deployments, during deployment phase when we pause the deployment, the counter is incremented but when deployment is finished, it returns to '0'.
