[Pdns-users] pdns cannot handle large pdns notify

We make an important discovery, but we don't know the reason why.
When we do pdns notify *, we checked through all the logs in source server
in /var/log/messages, we realised the domain example.com was not send out
If we just do pdns notify example.com, it will be sent out.
Then we count the logs:
root at pdns-source [~]# pdns_control notify '*'
Added 563 MASTER zones to queue
But we realised "example.com" was nowhere in the logs as well.
grep "example.com" /var/log/messages (returns nothing).
Any idea why?

So you have the basic improvements. You might try updating one of your
slaves to 4.2.1 and see if things improve. Otherwise maybe pace the
notifies by a simple shell scrip *and* reallize missing a notify is not a
critical error since slave servers check periodically (SOA refrsh
interval) to see if they need to update.
