[lwip-users] netconnect_listen ERR_MEM w/ multiple sockets

[kenneth . jackson]

Here is my problem:

 

I want to create two sockets, one for an HTTP server and the other for Telnet.

 

Independently (only one of them has been compiled in),  they both work.  However when I complied both in, one will work and the other will return a

ERR_MEM ( Out of memory error) code after calling netconn_listen( struct netconn *conn ).

 

As you can see from the following code snippets, the functions are pretty much the same except for the port #.

portTASK_FUNCTION( vBasicTelnet, pvParameters ){

struct netconn *pxTCPListener, *pxNewConnection;

pxTCPListener = netconn_new( NETCONN_TCP );

netconn_bind(pxTCPListener, IP_ADDR_ANY, 23 );

netconn_listen( pxTCPListener );

....

}

portTASK_FUNCTION( vBasicHTTP, pvParameters ){

struct netconn *pxHTTPListener, *pxNewConnection;

pxTCPListener = netconn_new( NETCONN_TCP );

netconn_bind(pxHTTPListener, IP_ADDR_ANY, 80 );

netconn_listen( pxHTTPListener );

....

}

At this point, any direction towards the resolution would be very much appreciated.

I'm using lwIP 1.3.2.
