where: ** canis41 is syncrepl with canis39 (to keep both farms synchronized) ** canis41 and canis42 has delta-syncrepl between them (my idea is to switch off canis3x farm and then left just this delta-syncrepl)
The problem I'm having is with syncrepl between canis39 and canis41.
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.
