Re: UDP sendto problem

You might be out of kernel memory (try pinging your device. If only
small ping sizes work, then kernel memory is your problem.)

Use the latest version of xnetstack and - if you have a UDP socket bound
to a port - make sure you keep calling recvfrom() on the socket,
otherwise the unprocessed packet queue will consume a considerable
amount of memory.
