Hey Simon,
we have found another (small) thing. The requirements for reintroducing are:
1. Using --use-stale-cache
2. A query is received via TCP
3. The cached record is stale
Querying the stale record causes the query to be "refreshed". However,
when, at the same time, the client disconnects (and the TCP fork exits
accordingly), the received reply will never be received and find its way
in the mother process's cache.
Could we postpone the shutdown of TCP forks in case a refreshment query
is still ongoing?
Best,
Dominik
