After setting up 2 servers with multi-master replication, I added them both to a DNS record so users will go to either server.
Both servers are replicating the NetscapeRoot DB to each other. I made a schema change to one and restarted it- only to see it hang. I waited some 15minutes, and then discovered with netstat that it had a bunch of open ldap connections to itself, which weren't timing out or going away.
After I removed the IP from DNS (disabled round robin dns) for the server I was trying to shutdown , the server shutdown right away.
I'm guessing somewhere there's a configuration that needs to be pointed to the other master server?
How are others doing load balancing/fail over ?
