Unbound does not pre-fetch expired records. They are fetched normally, i.e. when a user asks for it. So the cache flush does not cause lookups. It also does not cause pre-fetch. When a record is 'near expiry' then a pre-fetch happens (if prefetch is enabled). This pre-fetch only happens when a user queries for that record. The pre-fetch does not happen if the user does not query for the record. For that 400 queries part of the report. So unbound will only generate an outbound query (except for trust-anchor updates on schedule) when there is an inbound user query. Also for pre-fetch. So, those 400 queries would only happen if the user is performing 400 lookups. I am trying to deduce what unbound would do in theory. If in practice this is not happening, some bug hunting is required. Does the user have real data or are these his estimates? Perhaps his mobile performs a lot of lookups when it connects to a hotspot, which is possible, with, I don't know, a lot of apps.
