+% CONFIG_LOG_CONFIG_ERRORS error(s) in logging configuration: %1
+There was a logging configuration update, but the internal validator
+for logging configuration found that it contained errors. The errors
+are shown, and the update is ignored.
+
+% CONFIG_GET_FAILED error getting configuration from cfgmgr: %1
+The configuration manager returned an error response when the module
+requested its configuration. The full error message answer from the
+configuration manager is appended to the log error.
