Hi.
i'm using socket on lwip 130rc1.
i have this problem:
after some send operation, in tcp_enqueue, here:
/* If total number of pbufs on the unsent/unacked queues exceeds the
* configured maximum, return an error */
queuelen = pcb->snd_queuelen;
/* check for configured max queuelen and possible overflow */
if ((queuelen >= TCP_SND_QUEUELEN) || (queuelen >
TCP_SNDQUEUELEN_OVERFLOW)) {
LWIP_DEBUGF(TCP_OUTPUT_DEBUG | 3, ("tcp_enqueue: too long queue %"U16_F"
(max %"U16_F")\n", queuelen, TCP_SND_QUEUELEN));
TCP_STATS_INC(tcp.memerr);
pcb->flags |= TF_NAGLEMEMERR;
return ERR_MEM;
}
my code loop forever, in this piece of code, with queuelen =
TCP_SND_QUEUELEN, without send any packet, incremeting err in tcp.memerr
i cannot recovery this situation?
my thread is blocked on send operation i suppose....
bye,
Piero
