When there is a burst of DNS requests, We are noticing steep memory

If i disable ‘proxy.config.hostdb’ , can this result in skipping the
complete hostdb module from processing
dunno - but this database and code should not exist at all - imagine a
world where every piece of serversoftware brings it's own
host-cache-database instead just use the configured resolver and let
caching be it's job
in-memory caching of hot dns requests is fine to not have a dns query at
every incoming http request - but a persistent on-disk database is
questionable to say it nice
