Re: [lwip-users] Re: Problem with recv (2)

[Oscar F]

Hello , i have tested to change the order in the arry of port and the application get worse!!, horrible, blocking in the accept, and if pass the accept never receive and the task delete!! the task is destroyed because the program follow and not enter never in my task. It´s very rare!!!

another thing i´ll give more stack to my task and no enter never in the creation.  My fixed memory is 46K and the total is 64K, i suppose FreeRTOS use dinamic memory too.

where is the limit to stack?, where is it defined?, i´m completly lost

Can you help me? any suggestion?
Thanks

Oscar

I didn't mean that you should actually get the customer to change their
application, just for you to experiment with doing things in different
orders so you can work out if it is the port numbers that are important,
or the order that is important.  If you don't have access to the client
to change the source yourself, just write a little application of your
own to connect to those ports.
