[ovirt-users] oVirt upgrade problems...

Hi at all, I have many problems after upgrade ovirt version. I come from 4.3.5.2. When I upgraded to 4.3.7 my three host (hyperconverged emviroment) I passed a few days of instability: HA agent down gluster problem... When I rebooted for the umpteenth time (after reinitialized lockspace, heal, heal full...) all cames up ha agent and broker included. Two days after arrived 4.3.8, so i decided to start the update, america with success, europa after a various problems (as described before) came up. Asia host, after 30 second of updating the engine goes down together with all three nodes ... Are there any known important bugs?
