I dont know about that, is that maybe because I had both addresses down as endpoints?
I have modified app.config on both machines to only point to one another: / <discoverySpi type="TcpDiscoverySpi" networkTimeout="30000" joinTimeout="60000"> <ipFinder type="TcpDiscoveryStaticIpFinder"> <endpoints> <string>10.0.2.5:47500..47502</string> </endpoints> </ipFinder> / <discoverySpi type="TcpDiscoverySpi" networkTimeout="60000" joinTimeout="120000"> <ipFinder type="TcpDiscoveryStaticIpFinder"> <endpoints> <string>10.0.2.11:47500..47502</string> </endpoints> </ipFinder> </discoverySpi> Now on the #11 machine the log is a lot cleaner, it just has these messages repeated: [11:17:08,959][INFO][tcp-disco-srvr-#3][TcpDiscoverySpi] TCP discovery accepted incoming connection [rmtAddr=/10.0.2.5, rmtPort=53509] [11:17:08,959][INFO][tcp-disco-srvr-#3][TcpDiscoverySpi] TCP discovery spawning a new thread for connection [rmtAddr=/10.0.2.5, rmtPort=53509] [11:17:08,959][INFO][tcp-disco-sock-reader-#24][TcpDiscoverySpi] Started serving remote node connection [rmtAddr=/10.0.2.5:53509, rmtPort=53509] [11:17:08,965][INFO][tcp-disco-sock-reader-#24][TcpDiscoverySpi] Finished serving remote node connection [rmtAddr=/10.0.2.5:53509, rmtPort=53509 But on the #5 machine the log is entirely void of any detail at all: [11:14:56,534][INFO][main][IgniteKernal] Non-loopback local IPs: *10.0.2.5*, 10.0.75.1, fe80:0:0:0:0:5efe:a00:205%net2, fe80:0:0:0:0:5efe:a00:4b01%net7, fe80:0:0:0:35b8:b554:51fb:2fc1%eth5, fe80:0:0:0:812a:7edf:9502:2449%eth4 [11:14:56,534][INFO][main][IgniteKernal] Enabled local MACs: 00000000000000E0, 000D3A18192C, 00155D02051F [11:14:56,571][INFO][main][TcpDiscoverySpi] Connection check threshold is calculated: 2000 [11:14:56,588][INFO][main][TcpDiscoverySpi] Successfully bound to TCP port [port=47500, localHost=0.0.0.0/0.0.0.0, locNodeId=c77edb8f-56b8-405d-b2ba-66f585a30952] -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
