 I loaded a large zone into the sqlite3 database (cz.) and set a slave
 server to refresh from it every second. So it sent a request for SOA every
 second.

 After few successful queries, bind10 reported that the cz. zone does not
 exist (sorry, I don't have the exact logs :-(). The next query took quite
 some time to answer, but it succeeded.

 I have two theories what might have happened. Either the hotspot cache got
 flushed and there came a query, before it got answered, another one came
 and the DB was locked, so the second one answered immediately as not-
 exist.

 The other is similar. I opened the DB with sqlite3, so maybe it got locked
 for quite a long time.

 However, both should probably be SERVFAIL, instead of pretending not to be
 authoritative for the zone.

 This might solve itself by switching to the new datasources, or might not.
