Description: LDNS memory usage level that triggers reaping, in bytes.
What is globalLDnsHiWater?
The amount of memory, in bytes, that the cached LDNS (local DNS resolver) table can grow to before 3DNS starts reaping older entries. Raising it lets the system remember more distinct resolvers before trimming begins.
