[Users] oVirt vdsm network problem

Hello, I found strange problem in vdsm 4.13.0 with oVirt 3.3.1. After 30 hours from update (ovirt -> 3.3.1, vdsm -> 4.13) my one vlan network does not work. There is nothing in log, I can see network trafic from not working vlan on node in tcpdump, but it not come to VM. After vdsm restart on node it works like expected. I take a look in to oVirt -> Host -> Network Interface and all nodes has bond interface changed from "Mode 4 Dynamic link agregation" to "Custom: mode=4" and Custom mode is filled by "mode=4" Mabe it is the same, but who change that? I can have one node in this status if someone will want more info or logs.
