I think that all became clear now. After additional debugging I saw that
the memory for the buffer is release from the function input() and I
actually make a second release. This causes the problem. I organized now
my code in the right way and I don't see any problems. However, more
tests are
Simon, you gave me a great advice. I knew that I have to check my code
and I made this many times unfortunately without result by now. But your
words "check your code if there's something that could overwrite these
fields..." focused my think in another direction. When I want to give a
frame

I need some help to understand how the stack works, because I cannot
understand what I see when I'm debugging my problem. The situation is
the following. I stopped on a breakpoint when when I receive an
acknowledgement from the PC and I' looking in the content of the
corresponding pcb,
When I'm looking in my code, I think that this was exactly the problem
that I have solved. Nevertheless, I removed my changes and I used the
original state of the stack. I have the same problem again, so now I'm
sure that at least my changes are not the reason for the problem that
I'm trying

Yes, the pbuf is not what I expect to see. The length doesn't match and
the content too. But I checked the higher level function and it seems to
receive the correct frame during the call of the input function. Then

This is not "our" lwIP, how could we support it?
As you correctly found out, the pbuf is somehow corrupted. I'd start to check

I'm still fighting with my problem. Now I know what is going wrong, but
I cannot find the reason. Probably somebody can help me. I attached a
Wireshark log. You can see that communication stops after the

If you want the server to accept 6 simultaneous connections, you have to
provide the stack with room for at least 6 pcbs, memory for the 6
connection structures, perhaps enough pbufs for prompt response...

I need some help about the usage of the HTTP Server. My current problem
