[Xen-users] ugly network bug

[Christoph <mangel@xxxxxx>]

Hi All

I have a really ugly bug here. After a lot of traffic to my nfs server 
in a domU I seet this in dmesg of dom0:
[179445.246983] vif vif-2-2 vif2.2: Guest Rx stalled
[179445.247024] xenbr2: port 3(vif2.2) entered disabled state

and this nic doesnt work anymore in the domU. This ist the nic what my 
nfs uses to share the fs...
I need to restart the domU then it works some time...

I have already tried these settings in dom0 AND domU:

/usr/sbin/ethtool -K enp0s25 tso off gso off

It doesnt fix it...

What can be the problem? How can I fix it?

The dom0 is a centos7 with xen info:
