Here I describe the situation on a HP Proliant with 16GB RAM. openSUSE 11.2 x86_64 dom0 with one (PV) openSUSE 11.2 x86_64 domU. Network configuration uses a bridge br0 with the dom0 and the domU network interfaces added to the bridge. When for example, copying a large file on the dom0 with scp from the domU to the dom0, the system dies. A log captured via a serial port is attached. I will repeat the experiment on the other machine (Super Micro based PC) and provide that log file as well. Reproducible: Always Steps to Reproduce: 1. Boot system and login as root 2. xm start domu 3. scp domu:bigfile . Actual Results: System is not responding anymore Expected Results: A stable system -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
