I still have some issues with n-way replication. It seems that after a
modification to the dataset contextCSN is not propagated to
peers. With a standard syncrepl after a modifcation I see the
propagation, but not with n-way replication.

With n-way replication the contextCSN gets modified on the present
master, but not on the peers:

initial contextCSN on localhost
contextCSN: 20081022151212.263032Z#000000#000#000000

initial contextCSN on remote peer
contextCSN: 20081022151212.263032Z#000000#000#000000

after a modification on localhost
entryCSN: 20081022151026.029523Z#000000#000#000000

on remote peer
contextCSN: 20081022151212.263032Z#000000#000#000000

I just wonder wether this is a new bug or is it silly me.
