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 .
