I have also upgraded to pdns recursor 3.2 yesterday. And today, I have a strange
problem on some of my systems. It seems be related to tcp DNS as the only thing
that stopped working is using tcp dns queries. The rest of the system worked

I have restarted pdns recursor and it fixes the problem.

I will do further testing if the problem happened again.
