I looked into this a bit more:

We have three MMR nodes, let's simply enumerate them as 1, 2 and 3.

When modifying a group entry on 1 'memberOf' gets *locally* updated and the
contextCSN value for server 1 gets also updated. So far so good.

Now the group modification are pulled by 2 and 3 and slapo-memberof installed
there *locally* updates attr memberOf and the *local* contextCSN value for 2
and 3 are updated with new timestamp. But the updated contextCSN values of 2
and 3 never get replicated to the other instances! So my monitoring check
shows a long-lasting replication gap. After next server restart all contextCSN
values get updated.

Sorry, glancing over ITS#6915 I don't understand what it means in this context.

Ciao, Michael.
