I've updated my virtual network (in Xen) to 3.12.6 few days ago and start encountering strange behaviour: random machins lose access via IPv6 ULA addresses to random others, until the moment, while losed machine itself pinged machine that search for it. IPv4 and link-local addresses worked okay. I've downgraded all of them to 3.12.5 and all going to work properly until tonight: two machines mutually losed each other (even mutual ping doesn't help) until I rebooted both of them. So, 1) I guess it can be some bug in 3.12 or hardened patches for it 2) Doesn't enybody else experienced same behaviour? -- Best regsrds, mva
