I am getting below warning in my Elasticsearch cluster logs.
[Warn] [o.e.x.s.t.n.securityNetty4ServerTransport] Send message failed send message failed [Channel: NettyTcpchannel{localAddress=0.0.0/0.0.0.0:9300}, remote address=IP:port]] java.nio.channels.ClosedChannelException:null
Can someone please guide me what is root cause of this.
