For us "something" started at 23:30 CET, resulting in more queries of type PTR and DNSKEY on our two authoritative servers. The problematic resolver was very sluggish and showed much more recursing clients than usual. I haven't had much this workday to even finding there is a problem at all, so I don't think it's necessary to pull it from the dlv. 

I've flushed the cache of the resolver and the query load dropped to normal level immediatly. Heres a graph (from on of our authoritiative servers). Maybe though this has nothing to do with signing of arpa. at all - I simply haven't had time to debug this harder.
