Re: [lwip-users] httpserver problem

Richard:

I reference to "basicsocketcommandserver" , it is almost as mine. So I suppose 
mine code is fine. But I also found some problem.
1. configTICK_RATE_HZ, the DEFINE value is 1000ms , It means switching task 
when tick trigger. So I change it to 5ms. 
2. my server code for dealing with GET command will send a big of data, and 
those data is defined as global variable 
So It is possible for lwIP hang when new TCP coming but old TCP is not handled 
done yet..

Does it make sense ?

FreeRTOSConfig.h will be irrelevant.  sys_arch much more relevant.

There are some FreeRTOS examples that demonstrate socket usage in a
multitasking environment - although thus far only a command interpreter,
so nothing that will put the stack under the same load as an HTTP server
has the potential to do.

From what I have read on this list, the normal answer seems to be, there
could be a threading issue with the way your interrupts are interacting
with the stack.
