* I have a farm with syncrepl running for years without any problem.
farm is running 2.4.43. Servers of this farm are named canis3x
* I have a new farm with servers named canis41 and canis42 (with 2.4.47),
** 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.
usually works well, unless the device is configured to close idle
connections at less than a 5 minute interval.
