The netconfd-pro server is reporting this error because its startup-cfg.xml file contains reference to the /toaster container, but the server is not loading the toaster module at boot time.
To fix this you can do one of the following:
1) load the missing module at boot time using the module parameter, i.e.
> netconfd-pro module=toaster
2) instruct the server to load the toaster module at boot time by adding the following line to to netconfd-pro’s config file, /etc/yumapro/netconfd-pro.conf:
3) start the server with a clean startup config, i.e.
> netconfd-pro factory-startup
