Ignite starts off with a default port, and then starts incrementing it with every new node started on the same host. Perhaps you start server and client nodes in different order sometimes which causes server to bind to a different port. To make sure that your server node binds to the same port all the time, you should try specifying it explicitly in the server node configuration, like so (forgive me if this snippet does not compile): > > > > *<property name="discoverySpi"> <bean > class="org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi"> > <property name="localPort" value="40123"/> </bean></property>* Please make sure that the client nodes either don't have any port configured, or have a different port configured. You should also make sure that Ignite always binds to the desired local interface on client and server nodes, by specifying IgniteConfiguration.setLocalHost(...) property, or like so in XML: *<property name="localHost" value="my.local.ip.address"/>* If my theory is correct, Ignite should make sure that the clients and servers cannot theoretically bind to the same port. I will double check it with the community and file a ticket if needed.
