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.
Hi!
I don't understand that: Keepalive (as I know it) has nothing to do with idle
connections, but only with dead connections. And what's the magic with 5
minutes?
