The length of payload data of a control frame is greater than 125 bytes.

I am trying to send data from websocket-sharp to a https://github.com/statianzo/Fleck server and it will not send a large amount of data over websockets. The byte length of the message is close to 16000, so I am not sure if that is absolutely too large or if there is a way to send it in multiple messages.

Also should mention that it seems to send data when it is past 125 bytes normally...I have sent 251 bytes, 300 bytes, 287 bytes

Here is a image of the error message.

Could you show me your client side code?

And that error occurs when the client receives a control frame (ping, pong, or close frame) that has a payload data which is greater than 125 bytes.

So, you should know what control frame does your Fleck server send to the client after the server receives those data.

The issue went away...not sure why. I'll let you know if it happens again.

I've got the same issue when sending message with string length 75695. It's pretty big message, but should be still valid. I get the same exception on NetworkStream.Write(). I am working on client app. Our server uses java Play-Framework built-in WebSockets. Network Monitor shows that data is not even sent to remote host yet.

I'm not that good at websocket standarts and stuff, but it seems like exception happens when writing final segment of a fragmented message ( send (Fin.Final, Opcode.Cont, buff, compressed); WebSocket.cs : 1227 )

The issue does not go away.
Here s exception info. Sorry for non-english messages, it's framework locale. It says "NetworkStream Write Exception: An established connection was aborted by the software in your host machine"

Here's callstack

I've got the same issue when sending picture 19kb.
So is there any other way to send the picture?
