I don't have boxes at the moment and can't reproduce till Monday, but can you show us the output of netstat -uan and netstat -s on both domains? Is there stuff in the receive or send queues? And was all the udp traffic going to the same port? i.e. any successful udp traffic to another endpoint? I then start a UDP server in D0, and a traffic generator in D1. After the traffic generator sends its 128-th packet, networking between the domains fails. The 128th packet is received successfully by the UDP server, but no later traffic arrives in D0. This includes UDP, TCP, ICMP, and ARP. What does ifconfig on dom0 show? Are there any error messages in /var/log/messages? Looking at the interrupt counts in /proc/interrupts, I see that D0 no longer receives packets sent by D1. D1, however, does receive packets sent by D0. (To be clear, D0->D1 traffic is ICMP ping requests, unrelated to the UDP traffic. There is not UDP traffic sent from D0 to D1.) Is there any other successful traffic from D0 -> D1 (tcp?) thanks, Nivedita ------------------------------------------------------- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.
