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.
