Emergency Patch for: 'This Server is Unclaimed' (networking race condition)
systemd based systems, Centos 7, Redhat 22+ and Ubuntu 16+ , which boot very quickly (usually SSD-based) and where PMS is set to automatically start can experience a race condition which makes PMS report itself as Unclaimed. This occurs because the system has started PMS before all network components (the network stack and all adapters) are fully initialized and ready.
