Hello everyone,
I recently started using udpcast and so far am very impressed. I am however having a problem. When I try to udpcast to 5 clients, 1-3 typically give an error similar to the following:
Timeout notAnswered=[2,3,4] notReady=[2,3,4] nrAns=2 nrRead=2 nrPart=5 avg=10152
I've tried adjusting the transmission speed, multicast addresses, starting the clients before the server or vise-versa. So far it appears to be random which clients decide to "answer" and be "ready". Sometimes they all work, sometimes 4 work, sometimes only 1 works, etc.
the lab I am working in is connected though a cisco 4006. From what I have read cisco uses a proprietary IGMP implementation (called CGMP), could this be a cause of some of the problems I am having?
If anyone has any insight into this problem please reply.
Thank you, Mike

I have seen a similar issue, but in my case, it appears that one of my classroom systems has a hard drive that isn't able to keep up with the transfer speeds as well as the other machines when it comes to the blank space on the hard drive. I use the --max-bitrate=60M to get it to have minimal error messages. When not imaging that machine, I can usually set it to 80M and not get any or very few of these messages. Never seen any problems with this message, but it does slow down things. I know it is the hard drive, since I swapped it between two machine, and it moved with the drive. Exactly the same drive model, so, it is that particular drive.
