Hello ,

I have a configuration with xen with 2 domu .
One domu have a nfs server , Other have a ftp server .

When i try to write a big file to the nfs server ( so i generate a big traffic , on network and on disk )
dom0 and domU's become  inaccessible via network .

I have the same problem , via ftp when i put a big file .

On the console , i must make ifconfig pethX down/up to restore the network .

I'am using xen-3.0.3-0-4 on debian - etch .
Can you use rsync instead of NFS or FTP? Is your file transfer as large as 2 GB? While NFS is very useful for lightweight file transfers, it gets..... awkward for high-speed trasnsfers. Also, which version of NFS are you using? Have you optimized it at all?
