[lwip-users] Can't allocate socket anymore |

Hi,
I have one problem about create TCP socket.
I make one test client to communicate with server and it can work.
This is my test case process:
1. create one TCP socket and connect to server.
2. do some data exchange.
3. close socket.
But I always fail at the 4th run, because it can't allocate socket anymore.
struct netconn*
netconn_alloc(enum netconn_type t, netconn_callback callback)
{
struct netconn *conn;
int size;
conn = (struct netconn *)memp_malloc(MEMP_NETCONN);
if (conn == NULL) {
return NULL;
}
I try to increase pbuf, netbuf, netconn, but it's still failed at the 4th
run.
I also print out stats data before/after make connection, but I don't see
the error or leak problem.
I know that this issue has the same scenario (always fail at the 4th run),
but I just can't find the root cause.
Does anyone get the hint about my problem?
