Hi
we are doing some indexing on ES. I'm not sure is this some strange behavior or not, but sometimes i found following wraning and stack trace on ES master :
[18:17:24,808][WARN ][discovery.zen.publish ] [Gilmore, Ritchie] Failed to send cluster state to [[Marvel Boy][557814db-6921-4a3e-9910-82593b4a5064][inet[/172.17.1.16:9306]]{client=true, data=false, zen.master=false}], should be detected as failed soon...

I'm writing java app which indexes data with java api (it is threaded app, where 20 threads are doing write on index and each thread has it's own client).
Best
