Dear Sir:


I am testing UDP-sender.exe and UDP-receiver.exe under WinXP with following commands. But a error (marked by red color) happens after the server transfers data once. Under linux, I have never met this problem. I am wonder if there is a bug?



C:\Documents and Settings\hwsun.PSL-AD\Desktop\UDPCast-run>udp-sender -f test.tx

t -P 5004 -M --daemon-mode --nokbd --min-receivers 1
