Unexpected end-of-input in VALUE_STRING
I think the data source has been trimmed by some kind of limit, please check it. Anyway netty-socketio receives a half of string, i think.
was not called before it's garbage-collected.

9 years ago Thank you for the quick response. But that's not all :) 2 How to run the server as a daemon I'm used https://github.com/mrniko/netty-socketio-demo and I found a solution:
mvn exec:java
ctrl+z
disown - h
bg 1Maybe there is a better solution?
3 I tried to upgrade to version 1.7.5. But my code is not working correctly. Where you can read what has changed?) and sorry for my english)

It worked, thanks) How i can reboot server?
I think the data source has been trimmed by some kind of limit, please check it. Anyway netty-socketio receives a half of string, i think.
Before I added:
config.setMaxFramePayloadLength(10000000);
config.setMaxHttpContentLength(10000000);was an error:
Max frame length of 65536 has been exceeded.I think maybe data truncated, when the nginx passes the data to the websoket server
//nginx.conf
location /socket
{
proxy_pass http://192.168.0.34:3000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
}I'll check it out

4GB of memory on the server. This is not enough?

Usually you need to wrap your server in some kind of application and run it via service or with some app-container. All functionality (i mean .start and .stop methods) are provided by my lib.

May be it's your case? http://stackoverflow.com/questions/22563167/netty-bytebuf-dont-get-the-full-message-of-a-large-input-when-decoding

Looks, like I need more knowledge about linux:). Thanks.

I will raise test server, where the websocket server will run without nginx. Then write about the results:)

9 years ago | 2 How to run the server as a daemon Have you tried Procrun (for Windows)? It wraps a Java application into a Windows service that you can control (start/stop/etc) from the Windows Services control app. We use it with vey good results.

I added:
Configuration config = new Configuration();
SocketConfig socketConfig = new SocketConfig();
socketConfig.setTcpReceiveBufferSize(20);
config.setSocketConfig(socketConfig);
//another settings ...
final SocketIOServer server = new SocketIOServer(config);result: 1) error does not appear 2) But the file(Blob) is not uploaded
What value of the attribute(tcpReceiveBufferSize ) to use? For example, to upload 1 mb.

....I think, I found a bug. It looks like a bug in Google Chrome. In another browser (ff) everything(upload blob) works fine. I can not believe it :)

9 years ago probably a bug in Chromium. Opera and Chrome do not work FF и IE work well

9 years ago so setTcpReceiveBufferSize=10000000 helps to upload in FF and IE?

no. FF and IE work without setTcpReceiveBufferSize

9 years ago https://code.google.com/p/chromium/issues/detail?id=420578 Probably, the Chrome sends the fragmented message(when message > 100kb?) and Websocket server does not know to handle them. What do you think? Problem may be in this?
mrniko
commented
9 years ago as wrote in comments it's 128Kb limit. In your case the string has end at 129981 or 129981 byte, so i think it's really this issue.

If I replace the *WebSocketFrame classes in netty-socketio to ContinuationWebSocketFrame class, it can help?
1) I will try to use a different socket server (nodejs or php) 2) and try to write a working example for https://github.com/mrniko/netty-socketio-demo, which will appear this error

}To reproduce the error: 0) mvn exec:java 1) Open chrome 2) ctrl+shifr+i (open console) 3) execute code:

Hi. I use a framework(1.7.3 version) already some time and I have accumulated a number of issues:).
Client Side
Problem: when I upload a large file( ~150+kb ), the server generates an error
a) How can I fix this error? b) If several times to upload a large file (2mb) in different pages, server crashes:
How can I avoid it?
