does the buffer size of RX affects on disconnecting the TCP communication?!

[Saraa]

Dear All,

I am using PIC32 micro-controller as a client and a code implemented by LABVIEW to work as a server,, How ever the after many testing the TCP connections lasts for "30 mins" only and then it disconnects!!!

Does it relate to the RX's buffer size, I mean if it reaches the max size of sending data it stops?! even though I am using TCPFluch().. ??

waiting for your recommendations...

Thanks;
Sara

You would want to determine the cause of failure more exactly. As a first step, wireshark can tell which peer is actually behaving unexpected. I would personally expect a wrong implementation of the application layer on top of the MHCP stack.

thanks FvM for the reply,,
I will use wireshark, but I think that the problem comes from the micro-controller "PIC32"!...

I have used the wireshark,, and it shows that the problem is caused from the pic32 "client" ...

Any suggestions to know why it reaches a time out after 30 mins?! ... Again I doubt that RX buffer size has reached the maximum which causes the problem but I need to be sure!! any help!

O.K., but there's more information you can get from the dump. How is it failing exactly?

The important question is, do you observe a bug in the stack implementation or is it just inapproriate usage, e.g. scheduling more data than the stack can handle. Buffer size is just a detail aspect in my opinion.

I believe this is the case because there is no bug!
