William.
Many years ago we moved from mlp_tcp to tcp_cknak to communicate between Cloverleaf sites on the same server.
We found after multiple power outages during a *really* bad day that messages were ‘lost’ between sites. On investigation, we proved that killing a site communicating with mlp_tcp would lose the message – we believed that the message was in the TCP buffer and not in the Cloverleaf recovery database.
We used the same test scripts with the tcp_acknak PDL and could not reproduce the same message loss.
Note that we DID NOT use message acking between the Cloverlewf sites.
I hope this helps
