Looks like the limit for the Virtual IP is around 100.
I think that if I change my networking around and put the UDPcast server on the first interface, then the number of Virtual IP's will not play a role.

think i might have found the issue It looks like the number of virutal IPS is more that the udpsender can handle. I have removed all the virtual IP addresses from eth2 and now the sender will activate on eth3.

the network card has 192.168.9.254 associated to it, it also has 9 virtual IP as well 192.168.0.254 thru 192.168.8.254.
I will try the strace option.

This was working and now it has stopped.
Have a UDPcast server running on a HP DL360G5 with 4 NICS. One connected to an internal infrastructure (eth2) and another connected to a dedicated switch with the client systems on the same switch (eth3).
When i run the UDPcast send or receive, using the following command: udp-sender -f /home/base.udpc --interface eth3 --point-to-point -- full- duplex --max-bitrate 600m --nokbd --portbase=9922 --min-receivers 1 -- rexmit-hello-interval 5000 --max-wait 300
I get the following error message: Udp-sender 2007-03-23 No suitable network interface found The following interfaces are available: lo 127.0.0.1 eth2 10.46.0.251 eth2:1 10.46.0.1
Interestingly, an ifconfig show eth3 as a valid network adapter, but the udp-sender does not see the device. This was working last week, and nothing has changed on the server
I have tried everything, restarting DHCP, removing the interface and adding again. Rebooted the server, restarted the network stack manually. nothing seems to help.
Using SUSE linux 10 as the base server OS.
You can only use a network card if an address is associated to it. Is this the case? If so, which address does it have?
Could you also try running udp-sender under strace and send me the output?
