Dear All, I'm using udpcast for 1.5 year now and since I upgraded to a 3.2.x kernel, I'm experiencing some weird issue on udpcast. The setup didn't changed at all since the time it worked except the kernel (same hw devices / network /..). The behavior we saw is that after a while (~ 30Gb of data) some clients looks like frozen. We started to investigate on it and the can see the following: - the multicast stream is still reaching the host (proc/net/igmp is ok, tcpdump -pni show the traffic too) - the udp-receiver seems block on a read() call - udp-cast doesn't exist due to wrong data even if the timeout is specified (the timeout worked by the past) We are using 2011.07.10 version of updcast for a while now. It didn't got changed since the time it worked. Does anyone experienced that or does some have some ideas to understand what's happening ? Thanks,
