Hello,
I have problems with web server on my G120HDR. After couple of requests web server always stops responding. Is there any reliable web server running on top of mnfm? Can I use Gadgeteer.WebServer? Thank you!
@ Adam - Can you post a minimal program that reliably shows the issue you’re having?
Hello,
I have serious problems with sockets. Always, after about one hundred requests main loop of my web server freezes (comment in my code below). I would appreciate any help…
Firmware version:
4.3.6.
Hardeare configuration:
G120HDR Module Rev2
MicroSD Card Module 1.2
CAN DW Module 1.2
ENC28 Module 1.1
I have read very long discusion about nearly the same issues what I have: https://www.ghielectronics.com/community/forum/topic?id=12342&page=1
Unfortunatelly I didn’t found solution. My code is here:
//ThreadStart method
private void StartServer()
{
socket.Listen(int.MaxValue);
while (!cancel)
{
bool pollOk = false;
try
{
pollOk = socket.Poll(-1, SelectMode.SelectRead); //stops here forever
Debug.Print(counter++.ToString());
}
catch (Exception e)
{
//No exceptions here
Debug.Print(e.Message);
return;
}
if (pollOk)
{
processRequest(this.socket.Accept());
}
}
}
Output from VS (last few lines:)

I am also reading data from CAN bus every two seconds. It is realized by Threading.Timer. I think that reading CAN bus has minimal impact.
@ Adam - To be sure, can you take everything out of your program except networking?
Socket snippet is confusing me…
You do a listen on the socket, turning it into a socket for listening for incoming connections.
You then wait on the listening socket for something to read?
Usually after a socket has been made into a listener, you do an Accept() against it, which returns a new session socket when a new connection is made. You would then do reads against the new session socket.
Code copied from here also didn’t work.

I have just created new project with only web server. No CAN Bus, no File streams. Few requests and bye bye…
On the web browser side i have page with ajax like:
[em]
I am curious if problems causes HW or SW.¨
@ Adam - are you asking us to debug a web server you found on CodePlex?
I think you will get better responses if you make you requests for assistance more specific.
