Comment 51 for bug 218126

I am experiencing the same problem as Wolfgang two posts above. Unsure if it is related to bug 218126.

Running stock feisty dom0, upgraded domU to hardy and now having this problem. Tried Hirano Takahito's kernel on the domU yet the problem subsists.

The server is quite heavily loaded as a web and mail server, but operates fine until one of the 12-hourly rsyncs occur to back up the database. At the backup times, there is about a 50% chance that the network connection on the domU will become inactive during the transfer. The only way I have found to restart the network connection is destroy and recreate the domU.

Through the domU console, tcpdump shows arp packets being received by the domU but nothing sent out. ifconfig shows number of packets received increasing slowly (with the arp requests) and number of packets sent not increasing.

This domU has run fine on a feisty for a considerable time, and only started to exhibit this problem after upgrading to hardy.
