The problems deal with pbufs from the pbuf_pool. I'm using the raw API to access
them. It looks like if PBUF_POOL_FREE is not freeing those pbufs allocated in
pbuf_pool_alloc_cache. 

I'm connecting a tcp server communicating through lwip stack with a client in
other machine. When I reach x executions of the client, I receive the message
said before. ?¿?¿?? Maybe is not too mucho info. Thanks anyway. If it's a bug,
I'll post it. Bye.
