I think it's more likely a bug in the _old_ kernel.
Considering you're running a set of squids, I'd expect the traffic to be
biased in one direction; think about this:
An empty cache has to fetch content before serving to the clients;
inbound and outbound of the cluster as a whole is likely to be around
the same.
A "full" cache (that is, one where content is starting to expire) is
likely to show far more traffic destined towards the clients than
destined towards the cache.
I find it rather surprising that prior to your new kernel the traffic
was identical in both directions.
What figures is your graph showing, exactly? Is that the traffic on the
director's interface(s)?
