[lwip-users] I free all pbufs that I reserve but pbuf_pool is full !!

[Sergio PérezAlcañiz]

Hello, as I say in the subject, I count the calls to pbuf_alloc and pbuf_free
and are almost the same, but, at the end, I got the message: "pbuf_alloc: Out of
pbufs in pool,". When freeing pbufs I see if the pbuf->ref is greater than 0,
but it is not, so they are suposed to be freed. What is happening??
