Looks like, I've got it. We had some misconfigured services asking
stupid invalid DNS queries from the ISP, also the user activity has
risen since we upgraded from 128kbit to 256kbit recently. I've fixed
the misconfigured services and added "DNSCONF=para:8" to the dns proxy.
Tested it with a few hundred almost simultaneous requests and so far it
looks to be ok! :)
