[riot-users] Posix Sockets problem

Hi Oleg,

Thanks for your answer,

I am currently using posix-sockets in native with desvirt to create my network's topology.
I don't think I had the same problem with gnrc_networking (without POSIX sockets) but I decided to use POSIX sockets to receive the udp payload in the application's thread and be able to print it or do extra calculations with it.
Are you using POSIX sockets too or the gnrc_networking example ?

Right now, I have no idea what could go wrong. In fact, I could successfully
run experiments over 7 days with 10,000 pings. Which hardware are you using?
Have you checked if you experience the same problem without POSIX sockets,
e.g. using the gnrc_networking example?

The worst part about token ring jokes is that if someone starts telling one
while you are telling yours, all joking stops.
