When a page is requested, some of the links (fnid=X) map to functions on the server that are held in memory. The id (X) is a key that is associated with a continuation for a specific "session".
It's not a bug, but a feature of Arc and other continuation servers. If continuations aren't reclaimed by the server (and those links invalidated), the server runs out of RAM.
