Hi Bert,

Can we use pdns-3.0-svn.20070915.1092.tar.gz downloaded from
http://svn.powerdns.com/snapshots/1092/ as a production release?

Hi Jaco,

Would it be possible for you to try with 2.9.21?

Most definitely. What is probably happening is that your slave loop is

Yes, it should most definitely be possible. Do you actually have 150k slave
zones? What is probably happening is that the slave loop is continuously
polling the state of 150k zones, or trying to transfer them, which causes
the loop to take a few hours to run - which is why your system is reacting
so slowly.

Please let me know if this description of your configuration is correct - I
know there is a powerdns user out there that used to run into a similar
problem, and they solved it.
