no ;-)) i want bind to be up while i´m doing a "reconfig" ---- not while i am
restarting the pc..... the problem is:

i start bind with 5000 zones - then it´s running... now i want to add over 50.000 zones...
okay.. that´s no a typical way of using bind - but anyway... now i do a "reload" or reconfig...
bind starts to load the 50.000 zones... but in __this time__, i am NOT able to "dig" one
of the 5000 zones bind already loaded before...  ------> that´s the big problem...
the NS will be unreachable for some minutes...;(((

how can i solve this problem ??

thx for any help !!
