Any further clue?

I started seeing this "too many frags" error popping up in dom0's over the last few months, when using the latest 4.2 builds. I've seen it with both Linux (various distros) and Windows domUs. For me, usually it results in Xen disabling the network adapter.

The workaround that I use is turning off TSO/GSO inside the domU:

ethtool -K eth0 tx off tso off gso off

You may also need to turn off GSO from the dom0 side:

ethtool -k vifX.0 tx off gso off
