Well, my last try wasn't this effective... The resolver still hangs in sceNetResolverStartNtoA after a few tries (highly random).
I tried to create the resolver only once and reuse it, same effect.
Does anybody have a hint on this ?
Here is some sample code, adapted from the resolver sample in pspsdk:
