Hi all!
I have problems with the instances of elasticsearch because I don't have free space in the server. When I analyzed the files, I saw that it has a lot of files with the termination .hprof.
Which is the meaning of this files and how can I reduce it?
I use the opportunity to understand if anyone knows the meaning of these logs.
_[2020-02-03T13:08:44,059][WARN][o.e.h.n.Netty4HttpServerTransport] [Protoss] caught exception while handling client http traffic, closing connection [id: 0x7d461090, L:/XXXX:9200 - R:/YYYY:55235]_
I have 2 servers and I understand that I have a connection between them, but I don't undertand the problem, I opened the ports 50.000 to 60.000 but still I have the same message.
Thanks for the help!
