[Udpcast] UDPcast sender freezes

Dear friends - I have a problem.

My UDP-cast is working very vell from PXE (that's not the problem). The problem is that after a while 2 - 30 GB it surdently freezes and I can't get in touch with the mashine via the keyboard or anything. And the cloning-proces stops. I worked at is the whole night the other day (to 4 morning), but it keeps doing it. First I used a version 2 month old, then I updatet to the newest at that time (20070306) but is kept apering. I use no command-line-options and it is a switch with 20 mashines.

Any sugestions about what could be wrong?
