I'm running version 2.9.22.
In our case the remote connections where all coming from argus.sidn.nl.
This is a machine (as you probably know) of the .nl-registry which AFAIK
excutes zonechecks for registered .nl-domains.
It hasn't happened since but I will do some more testing next around,
assuming a next time will come.
I'll start a new thread if/when the problem occurs again. If I need to
collect specfic information just let me know and I'll try.
