your fileserver is talking to your clients
you copy in a new CellServDB
your fileserver becomes less interested in talking to clients and goes off 
into a kcorner and talks to itself a lot

it cannot, actually. it can cause every server to need to be restarted
bjut the tokens in the client cache will still work after the new servers 
start

unless you have a dumb client which is "clever" and throws away its token

but that's not the server;'s faulty

also, i should pribably answer when i am more sober
