We don't have load balancers yet, but we have cross site replicas that suffers 
many client reconnecting when one side is failing and are considering adding 
both replicas and lb in front.

Thanks for the point.

I won't disagree with Howard, who knows a lot more than I do about OpenLDAP.

But I do want to add that if you do have a load balancer, and you do see these, 
then check if your load balancer is using SNAT to manage client connections. 
Usually load balancers do use SNAT.

In the case you see these errors and you are using load balancers that SNAT 
client IPs, then adding replicas is a good fix.
