Re: IP address changes

IP addresses are stored in CellServDB files on the clients and in the
memory of the AFS client cache managers.  Cache managers will never
forget an IP/port once they begin talking to it.  A restart is necessary
to make them forget.

If aklog or vos is using old addresses it means that the client's
CellServDB information is out of date.   Or that the equivalent data in
DNS AFSDB or DNS SRV records was not updated.
