It mostly depends what sort of pbufs. Most pbufs for tx data are PBUF_RAM, most pbufs for rx data are PBUF_POOL, so those are different classes of pbufs allocated from different places. The only likely time it seems possible to have problems with reception if you've allocated so many PBUF_RAM pbufs that the stack can't even generate an ACK packet. Unless you are actually allocating PBUF_POOL pbufs in your application or something like that, of course.
