Multi-Master Replication Startup Question

Hi Guys,

I am experimenting with Multi-Master replication of two ApacheDS 2.0.0.M15 instances, however I have problem starting both instances as replication consumers. Instance 1 is setup to listen for LDAP requests on port 10389 and instance 2 on port 11389. When the nodes start I see the following errors repeated every 5 seconds and a netstat -an | egrep "10389|11389" shows that the LDAP listening ports are not created.

Instance 1:

[12:58:26] ERROR [org.apache.directory.server.CONSUMER_LOG] - Failed to connect to the server localhost:11389, cause : Cannot connect on the server: Connection refused
[12:58:26] ERROR [org.apache.directory.server.ldap.replication.consumer.ReplicationConsumerImpl] - Failed to connect to the server localhost:11389, cause : Cannot connect on the server: Connection refused

Instance 2:

[12:58:14] ERROR [org.apache.directory.server.CONSUMER_LOG] - Failed to connect to the server localhost:10389, cause : Cannot connect on the server: Connection refused
[12:58:14] ERROR [org.apache.directory.server.ldap.replication.consumer.ReplicationConsumerImpl] - Failed to connect to the server localhost:10389, cause : Cannot connect on the server: Connection refused

prbayliss$ netstat -a | egrep "10389|11389"

I am able to trick the instances into starting up by starting instance 1 without being a replication consumer, then starting instance 2. I then stop instance 1 change it to be a consumer and restart it. Then both instances are running and netstat shows me the replication connections and the listening LDAP ports. Replication now works in both directions.

prbayliss$ netstat -a | egrep "10389|11389"
tcp4       0      0  localhost.10389        localhost.51051        ESTABLISHED
tcp4       0      0  localhost.51051        localhost.10389        ESTABLISHED
tcp46      0      0  *.10389                *.*                    LISTEN     
tcp4       0      0  localhost.11389        localhost.51050        ESTABLISHED
tcp4       0      0  localhost.51050        localhost.11389        ESTABLISHED
tcp46      0      0  *.11389                *.*                    LISTEN 

I've attached both configuration files. Is there a configuration option that I'm missing?

Many thanks in advance,
Paul

Re: Multi-Master Replication Startup Question

Posted by Kiran Ayyagari <ka...@apache.org>.
this appears to be a bug due to consumers on bother servers trying to
connect
to their peers before binding to each server's local port

can you file a bug report here[1] and attach your configurations.
