KVM and yes. I'm unsure if the problem is a result of conntrack fragmenting memory as it's tracking all the extra connections or just exhaustion of the virtio receive queue due to the peak in traffic as the torrents come up. Having said that even if virtio had to throw stuff away due to memory scarcity I would expect it to recover once memory returned. It's not as though the virtual machine hard OOOs. You can still log in via the serial console after the network has died. -- Alex, homepage: http://www.bennee.com/~alex/ Cleanliness is next to impossible.
