I enjoyed reading this but wouldn't have running either "netstat -s" or "ss -s" to show protocol statistic have shown either receive buffer errors/receive packet errors statistics? It seems like this basic tool was noticeably absent from the early troubleshooting steps and other standard troubleshooting tools used. I understand the importance of the ultimate fix but wouldn't seeing an incrementing error counter for UDP have shortened some of the troubleshooting done to identify and resolve the customer's immediate issue?
