bind crash with max-cache-size

[David Ulrich]

Hi,

I have deleted tes max-cache-size on friday from the config files of  
my dns servers. On saturday and sunday they died 4 times... in 9.3.4-P1.

Today I put a server on 9.4.3-P1 with some changes on config file  
(allow-query-cache and allow-recursion on the internal view) and  
another with max-cache-site to 128MB :-/ .

I'll give news after the next attack :) .
