Subject	F7 System crash with high network load

Hi,

i experienced it now a couple of time
that my Dom0 will get unstable if i copy a lot of files over a gigabit
link using rsync into the dom0.
That happens even, when there is no
workload on the system beside this process at all.

How to reproduce :

rsync -avuzP --delete --progress /home/user1
xenhost:/home/user1

the rsync will start and after a few
minutes the remote host (xen) is no longer responding on the network.
when i look at the console of the xen
host, it prints millions of :

[<c1005540>] syscall_call+0x7/0xb

only a hard reset helps now ..

environment :

xen-libs-3.1.0-2.fc7
xen-3.1.0-2.fc7
kernel-xen-2.6.20-2925.11.fc7
kernel-xen-devel-2.6.20-2925.11.fc7

so i assume it is a f7 kernel-xen bug
.. is this known, as i haven't found anything in bugzilla ..
should i open a ticket against f7 ?


thanks . Sven
