BIND 9.5.0-P2 DNS issue

[Daniel Dawalibi]

Hello 

The value of max-cache-size is unlimited. We installed another version of
bind on different servers, but we are still facing the same issue.

If you can stand to use a version of bind officially listed as beta, you
might try 9.5.1b3.  It fixes a bug in the cache cleaning and increases
the default max-cache-size.  As far as I can tell, it is not less stable
than 9.5.0-P2.
