heh.. tried that.. no luck :(
sigh..after yet a couple of hours trying to figgure this out, im 99,99% sure
that the problem is in lnp_addressing_write.
could this be that the function is not thread safe ?
but then again i have protected the function with mutexes (to ensure that i

ps: sending and recieving at the same time is has no problem after all :)

regards
a desperate kenneth johansen
