Yes, updating only one zone at the time is very much acceptable - that the initial transfer takes quite long time does not matter.<br><br>We do not want to use an "active" database due to memory / CPU footprint. If PowerDNS locks the table and let the other threads just wait for the lock like any other mutex it would probably be just fine with distributor-threads = 1.<br>
<br>I want to note that indeed PowerDNS _crashes_ / _exits_ in the end due to the "Database is locked" error. Since I'm currently testing with OpenDBX I don't know íf this is something that is regarded as an OpenDBX or PowerDNS bug - but gsqlite3 did also crash during heavy load which (as stated before) makes me believe that it's backend agnostic.<br>

</div>Like I wrote to Bert in a private mail:<br>
It doesn't crash but the handling of timeouts is suboptimal. I will create a<br>
patch that will improve this.<br>
