This will happen when all server are patched in the monthly patch rollout, so not action needed in that case. But be aware of any alerts of this type any other time. This notification has been very crucial in uncovering bugs in Update Expert <patching software> as well as other non-approved patch installations. Take action only if the alert comes at a time when no patching should be going on. |
