hi,we have a 4 member ignite cluster starting up well. but when we start extending above and as we add more nodes, we have couple of situations.1. Adding more nodes to the cluster takes time - sometimes upto 180-210seconds.2. Post 7 nodes - we can't add more - nodeCount oscilates between 7 and 6. The errors observed in one of the nodes are either"Node FAILED: TcpDiscoveryNode [id=01eb4646-67ca-4305-a2e8-8f100c958cea, addrs=[127.0.0.1, 192.168.10.21], sockAddrs=[/192.168.10.21:47500, /127.0.0.1:47500], discPort=47500, order=218, intOrder=113, lastExchangeTime=1487907499639" or "Failed to wait for partition map exchange ".we tried increasing ignite.failure.detection.timeout to 60000 but in vain.Also played with ignite.enable.network.timeout=true / false and ignite.network.timeout=30000.Searched the forums and found a similar post - but it said this is fixed in ignite 1.8 which we useWe are using ver=1.8.0#20161205..attached the log file from one of the nodes. ignite_out.txt <http://apache-ignite-users.70518.x6.nabble.com/file/n10852/ignite_out.txt> any suggestions or if we are missing something here we don't know, would be a great help.
