Hi All

I've been having some real issues with powerdns today, everythign was
working fine until I did inserted 16000 entries into the records table.
After a couple of reboots though, I'm still getting this.

It takes for ever to start up and then at the end it just exits. It
looks to me like there's a db issue given the "5015 questions waiting
for database attention" but the gmsql connections are successful.

Any help would be much appreciated. I'm kind of clutching at straws here
though, on the last reboot of the server, it took 30 minutes to run
through init, so it's behaving pretty oddly anyway.
