Well well well, I am sometimes soooo dumb. The RAW API is indeed not thread safe, this is explicitly written in the documentation, oh dear. To be honest, I actually based my work from previous code written, and yes, we now have to redesign "some" stuff in our products :-) Luckily, using the UDP raw API outside the lwIP thread, UDP being not a timeout-hungry protocol, seem to cope well.
