Hi,
I'm using lwip 1.3.0 and sometimes I have a pbuf overflow.
First of all, only to make sure what you mean, are you referring to the
PBUF_POOL running out of pbufs?
I'm not sure I understand the pbuf concept.
You have to call pbuf_free() on every pbuf chain passed to your
application (via the receive callback). If can chain two chains together
using pbuf_cat(), you only have to call pbuf_free() on the head of the
chain.
I have some data transfers
that exceed 1 tcp packet.
Every time http_recv is called I check if this is the 1st packet. If it
is I set a pointer to this pbuf and do not free this pbuf. If it is not
the 1st packet I store the data and free this pbuf.
What do you mean by 'store the data and free this pbuf'?
