Error: "write tcp use of closed network connection"

[qrpike]

Sometimes I am getting a
write tcp 10.2.51.9:9090->10.2.56.10:55088: use of closed network connection

I'm trying to figure out if this means the client disconnected during the writePump function? It seems to disconnect all users when this happens.

Thanks,

The error means that the application tried to write to the websocket connection after the underlying network connection was closed. The network connection is closed when the websocket connection is closed.

If the application has a concurrent reader and writer and one of them closes the connection, then it's typical that the other operation will return this error. The error is benign in this case. Ignore it.

A write to closed connection will not cause other connections to close. Something else is causing your users to disconnect.
