I'm already running 1.4.6.

Right now sheepdog is using a single bridged nic.
So setting netmtu may help.

My actual values are

        # How long before declaring a token lost (ms)
        token: 3000

        # How many token retransmits before forming a new configuration
        token_retransmits_before_loss_const: 10

Ok, thank you very much.
