This mostly tells the story. Your pdns_recursor has problems talking to the
network at sufficient speed. Either this is caused by you requiring too much
bandwidth, or by a firewall that gets upset by all the different UDP
'sessions' it sees.
Of 501k queries, 428k did not get answers. 352k were direct timeouts, 76k
were not even sent out by PowerDNS because it had a 'cached timeout'.

You should increase 'max-mthreads' beyond 1024 after you have your network
fixed, you dropped 31945 queries because 1024 were already running.
Fixing the network needs to happen upstream, this can't be done by PowerDNS.
