[lwip-devel] application above lwip too low - lwip memp overflow

[Piero 74]

Hi all

I'm testing performance of my lwip-application. I'm using socket (using select in a loop and recv) [lwip release: 1.3.0 stable]

I found a strange problem:

if i will send to my board packets very fast, after sompe packet i will have all pbuf of pool in use, and driver will not be able to add new packet.
But in this situation, i cannot recovery the stack...
my application after a timeout without packets closes the socket, but there is no way to free allcated pbufs
(see attachment)

there is something in the lwip head that can avoid this problem?

Thanks
Piero
