If the only problem is that bacula is eating all memory, than the kernel
OOM kernel should kill it instead of letting virtio networking die.
However, seeing how much similar problem reports with page allocation
failures in virtio there are on the web, not involving bacula, I would
rather suspect the problem is in virtio itself.
indicates that this bug was actually not fixed in reality, and that
using another network driver works around the problem.
