Sorry, I've just noticed this thread and did not read the earlier posts. 
I can see similar, although only (at least for now) on version 8 
(running something around RC2), also with bce interfaces and "heavy" -in 
terms of pps, this is a DNS server- network load.

Everything which involves network halts for some minutes, but the 
machine is completely usable from the console. top shows some processes 
(I don't have an output, but as far as I can remember they were only 
that which did network IO) in the "keglim" state.
Then something happens and the machine starts to work again.

Can this be the same, or is it completely different?
