I should explain why I said that.  Bind 9.5.0 introduced a new improved
cache cleaning algorithm.  It also set the default max-cache-size to 32M.
The previous default was 0 which means no limit.
It turns out that there is a bug in the new cache cleaning algorithm where
it can clean over aggressively when running into the max-cache-size limit.
More importantly, it can clean a just fetched value before it can be used.
Bind 9.5.0 fixes that bug and it also reverts the max-cache-size to 0.

If you have Bind 9.5.0 and do not want to upgrade, set max-cache-size
to some large value or to 0 to avoid the bug and to allow the cache
to be useful.  32M is a rather small size.

If Bind is set up to enable the rndc control program, you can get the Bind
version with 'rndc status'.  Hopefully the Linux distributors do not
diddle the version number.
