One of our replicas sits on the other side of a relatively congested WAN link
(with multiple firewalls in between, which I have no control over).

Since switching to syncrepl, it has been difficult to achieve a configuration
that supports replication reliably to any extent.

Using syncrepl consumer configuration with:

syncrepl rid=124
        provider=ldaps://<master hostname>
        type=refreshOnly
        interval="00:00:01:00"
        searchbase="<suffix>"
        scope=sub
        attrs="*"
        schemachecking=off
        bindmethod=simple
        binddn="<dn for consumer>"
        credentials="<password for consumer>"

I see replication dies frequently, it seems to occur when (for whatever reason)
the consumer fails to bind:
