TCP server crash - on reception of large number of data's

[Anonymous]

Hi

I just modified the tcp_server app

1. Once connected listens for data until disconnected from client side

2. Removed the echo back , prints the rxd pkt size only

I'm transmitting packets of 1K size to the server continuously without delays , and after some time ,say 30 sec , I see my server gets crashed and Platform gets restarted,

This behavior is only in Wiced SDK 3.1.0 but working OK in Wiced SDK 2.4.1 , But I can't use SDK 2.4.1.

How can I solve this issue? Do I require some patches to solve this problem?

static wiced_result_t tcp_server_process(  tcp_server_handle_t* server, wiced_packet_t* rx_packet )
{
    char*          request;
    uint16_t        request_length;
    uint16_t        available_data_length;

    wiced_packet_get_data( rx_packet, 0, (uint8_t**) &request, &request_length, &available_data_length );
    WPRINT_APP_INFO(("%d\n", request_length)); /* just prints the length of xrd packet*/
    return WICED_SUCCESS;
}

static void tcp_server_thread_main(uint32_t arg)
{
    tcp_server_handle_t* server = (tcp_server_handle_t*) arg;
    while ( quit != WICED_TRUE )
    {
        wiced_packet_t* temp_packet = NULL;
        wiced_result_t result = wiced_tcp_accept( &server->socket );
        if ( result == WICED_SUCCESS )
        {
            while(1)
            {
                if (wiced_tcp_receive( &server->socket, &temp_packet, WICED_WAIT_FOREVER ) == WICED_SUCCESS)
                {
                    /* Process the client request */
                    tcp_server_process( server, temp_packet );
                    /* Delete the packet, we're done with it */
                    wiced_packet_delete( temp_packet );
                }
                else
                {
                    wiced_tcp_disconnect( &server->socket );
                    break;
                }
            }
        }
    }
    WPRINT_APP_INFO(("Disconnect\n"));
    WICED_END_OF_CURRENT_THREAD( );
}

I think that you missed function call tcp_packet_delete

Hi

try this sample for your information

//-----------------------------------------------------------------------------

static wiced_result_t tcp_server_process(  tcp_server_handle_t* server, wiced_packet_t* rx_packet ) 

{ 

    char*          request; 

    uint16_t        request_length; 

    uint16_t        available_data_length; 

    wiced_packet_get_data( rx_packet, 0, (uint8_t**) &request, &request_length, &available_data_length ); 

    WPRINT_APP_INFO(("%d\n", request_length)); /* just prints the length of xrd packet*/ 

//----------------------- add this code  -----------------------------------------------------------------------------

  wiced_packet_delete(rx_packet); // delete packet data(alloced memmory )

//-------------------------------------------------------------------------------------------------------------------------

    return WICED_SUCCESS; 

}

But as you can see that the packet gets deleted after calling the function tcp_server_process()

if (wiced_tcp_receive( &server->socket, &temp_packet, WICED_WAIT_FOREVER ) == WICED_SUCCESS) 

{ 

    /* Process the client request */ 

    tcp_server_process( server, temp_packet ); 

    /* Delete the packet, we're done with it */ 

    wiced_packet_delete( temp_packet ); 

}

So I assume this is enough to deallocate the alloacated memory for TCP packets.

Yes,  I missed,

how about  "tcp_server_thread_main" stack size ?

Then try "making thread stack_size", WICED seems to use more stack in network applicaiton.
