Besides what you wrote in the rest of your mail, do you have any other
reason to believe this? Based on the information you've given, I would
suspect you're just seeing the normal (albeit ugly) effects of
saturating a DSL line.

Are your Linux routers doing any traffic shaping? When you're having
these problems, what is the bandwidth going over the DSL? Don't forget
to look at both upstream and downstream rates.
