Bug description:
init.lua:
gr = { port = 22003 }
function gr.udpserver()
box.fiber.detach()
box.fiber.name("gr.udpserver")
while true do
local msg, status, host, port = gr.udpsrv:recvfrom(1024)
if (msg ~= '') then
print(msg)
else
print("not a message ", status);
end
end
end
if (gr.udpsrv == nil) then
local sock = box.socket.udp()
sock:bind('0.0.0.0', gr.port, 1);
sock:listen()

local f = box.fiber.create(gr.udpserver)
box.fiber.resume(f)
gr.udpsrv = sock;
