If a resolver cache has a very large number of ECS records stored for the
same name, the process of cleaning the cache database node for this name
can significantly impair query performance. This issue affects BIND 9
versions 9.11.3-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.45-S1, and
9.18.11-S1 through 9.18.21-S1.
