Each time you send the 50 bytes, a pbuf will be reserved.
The pbuf will be freed up only after the successful reception by the host.
So if you don't wait for ACK, your pbuf memory will be consumed by many
consecutive transmission packets waiting for ACK.
You may as well check your low level driver if there is data sent which
should not be.
I am not an expert in LwIP, I am just guessing.
