Hello, I don't know about any format in which I should write this mail, so please forgive me if there's any format to follow.
I am using v8.0.43 in latest Amazon Linux AMI(2017.03), on m4.large instance. I have deployed modified example Chat application. Everything works fine as expected, but I feel websocket connections are not getting closed in some instances. I could see INFO logs from org.apache.tomcat.websocket.server.WsRemoteEndpointImplServer, wrt connection not getting closed cleanly. I've increased limit for no of files to 65536, both hard and soft limits. Num of connections for NIO connector is set to default. Num of files(sockets) opened are increasing, can see it with "ls /proc/PID/fd | wc -l". Am I missing any config? I understand some clients are not closing connection properly, but is there any way to handle this properly on server side? best regards.
