In my case it is the Linux client causing the problems (cannot tell yet if
it is only with udp, but I would think so). If I understand Daniel
correctly his latest testes were performed with FreeBSD client and udp. So
it may very well be a generel issue with udp?! Would this help narrowing
down the problem?
