Actually, I've given this some thought and I think I understand why this
number can increase - it is ip address specific only, so if new clients
appear from behind an ip that is currently "active", i.e. has a
persistance template allocated to it, these would also be allocated to
the already quiesced server. So, although I have assigned a weight of 0,
the persistence templates wouldn't expire until all traffic subsides and
goes away for longer than <persistence> seconds after the last
connection closed. Cumbersome, but at least I can understand what's
going on.
Looks like adding that patch (or upgrading to a kernel at least
>=2.6.11) would fix it - working on that now.
Thanks for your help!
