What happens when two NSUPDATE requests occur at the exact same time?
Note - I’m not a PDNS developer, so can’t comment on the retry thing (though it sounds useful). Specifically with the SQLite bit though, it’s not really designed for high write rates (with contention). If someone’s usage is becoming like that, it’d be a good idea to migrate the SQL backend to something with good write contention handling. (there are many options, though naturally I’ll point at PostgreSQL as being decent :>) Regards and best wishes, Justin Clift -- "My grandfather once told me that there are two kinds of people: those who work and those who take the credit.
