Error 8317
Machine ‘SHAREPOINT2013C (SharePoint – 43000(_LM_W3SVC_1458308317_ROOT))’ failed ping validation and has been unavailable since
So this has to do with the Request Management Service that runs on the WFE servers on SharePoint 2013. The Request Management Service is of no value since you only have one server. If you disable this service on your single server farm these messages will go away and your Web Application creation performance will greatly increase.
