None of your configurations set a keepalive. If you have any sort of load balancer/switch in between, they will often cut idle connections, and replication will stop until slapd is restarted. I recommend always defining a keepalive interval in the syncrepl stanza to avoid these types of issues. keepalive=240:10:30 usually works well, unless the device is configured to close idle connections at less than a 5 minute interval.
