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:
