Hi,

Today I finally was abale to start a second node in mij new cluster. When I curl to \_nodes I see 2 nodes and it seems like disks of the new node is rapidly being filled with gigs of data so that looks promising.  
However, when I look in mij log this line puzzles me:  
[2018-09-07T13:50:28,681][WARN][o.e.t.n.Netty4Transport] [pdbs247.grn.prd.itv.local] send message failed [channel: NettyTcpChannel{localAddress=0.0.0.0/0.0.0.0:54198, remoteAddress=null}]  
java.nio.channels.ClosedChannelException: null  
at io.netty.channel.AbstractChannel$AbstractUnsafe.write(...)(Unknown Source) ~[?:?]

Why is it there? Why a null with remoteaddress? And is it logical that after startup during this syncing, nog loglines are written to the log?

using 6.2.3 on RHEL7, no xpack  
Cheers, Eric
