Are contextCSN values on all replicas really in sync if changes were correctly replicated?
I've implemented a monitoring check used with normal MMR setup (OpenLDAP 2.4.35, own build on Debian Squeeze) which also checks the contextCSN values on all replicas compared by server-id.
Sometimes we observe, even in isolated tests, that contextCSN values for a certain server-id differ for quite a while (up to hours) even though the changes coming from that server were definitely replicated to all other replicas. After a while the contextCSN values get suddenly updated. Unfortunately this does not always happen.
Any hint is highly appreciated.
Still seeing this issue with OpenLDAP 2.4.36 that contextCSN values retrieved via LDAP differ for quite a while.
Restarting slapd immediately updates the contextCSN values.
Any idea?
Ciao, Michael.
