Yes. One of their engineers did mention that memory management was
definitely a problem for them ... And their bragging number is also a bit
far-fetched. I bet with the 3xxx type of boxes they can't support more
than 10000 active connections, each sending/receiving 40k of dynamically
generated HTML by websites like google/altavista.
And Stevens is the authority. Even if he's no longer around.
