Which would be the default.
But yes, because of the message "PingAck did not arrive in time",
at least this may be the right tunable.

But the real mis-configuration is that you apparently try to run

Without fencing, any replication link hickup results in data divergence,
aka a "split brain" scenario. You really want to avoid that.
