It's not a bug, it's more a result of how the bans (that what they are
called in Varnish 3.0) work. The bans will add to the list and bans are
discarded when they are older then the oldest object in the cache. So if you
have objects with really long TTLs and a lot of bans this list can get long.

If you have a lot of CPU usage this might the thing causing it. Otherwise,
don't worry about it.
