Hi Ciro. We've not heard of anything like this.

Could you set a server that does this to report to our Metronome setup as
described in
http://blog.powerdns.com/2014/12/11/powerdns-graphing-as-a-service/ ?

Does your Lua script do anything exciting?

Threads=16 is a higher number than we usually recommend, but this should of
course not matter. But perhaps the problem goes away if you lower the
number, and this would be good to know.

Thanks for your report!
