4:31 p.m.
I found this in vdsm.log and I think that could be the problem:

I partially solve the problem.
My host machine has 2 network interfaces with a bond. The bond was
configured with mode=4 (802.3ad) and switch was configured in the
same way.
If I remove one network cable the network become stable. With both
cables attached the network is instable.
I removed the link aggregation configuration from switch and change
the bond in mode=2 (balance-xor). Now the network are stable.
The strange thing is that previous configuration worked fine for one
year... since the last upgrade.
Now ha-agent don't reboot the hosted-engine anymore, but I receive two
emails from brocker evere 2/5 minutes.
First a mail with "ovirt-hosted-engine state transition
StartState-ReinitializeFSM" and after "ovirt-hosted-engine state
transition ReinitializeFSM-EngineStarting"
