PS: 82 MB/sec is not our bandwidth-limit. It still peaks there. Dont know why. Certainly not the drives. They work up to 200 MB/Sec (10 drives there).

Thanks to your tests I am really sure that its no network-code problem anymore. But what I THINK it is: The network is allocating buffers dynamically and if the vm doesnt provide that buffers fast enough, it locks as well.
Did anyone have a 100-liner which demonstrates this problem?
The output of `vmstat 1' when the thing starts happening would be interesting.
