Can you try http://wiki.powerdns.com/projects/trac/changeset/865 ?

I had pondered this patch long and hard before releasing but decided it
wasn't necessary. It has been tested for a few nights on the testbed and I
consider it safe, it did not affect our test results in any measurable way.

But still keep an eye on it.

I can only think of a race condition where the bad data would just arrive
behind the good packet, the new check guards against this situation.

Hmm, odd. I'll look into that separately.

Thanks for the report, I hope this will solve the problem.
