Package: linux-image-2.6.26-2-xen-amd64 Version: 2.6.26-17lenny2 Severity: normal
I'm running several servers (Dual Core AMD Opteron, 16G of ram) with Xen. Dom0 is debian lenny adm64. Today I tried to run a large backup in dom0 - copy NFS-mounted partition to a local volume group. buki:~# cd backup/ buki:~/backup# mount homes:/srv/homes src buki:~/backup# mount /dev/vg/homes-backup dst buki:~/backup# (cd src && tar cpf - .) | (cd dst && tar xpf -) This resulted into server crash in a few minutes. Crash is reproducible - if after reboot I try the same, same crash happens soon with similary-looking backtrace.
