Error in Application Control logs

Hi,

since 10.05.16 I am experiencing some strange errors in my Application Control logs: 

2016:05:20-13:01:42 utm-server afcd[27428]: vy_plugin: E: failed to parse DNS RR in answer section of length 16 at offset 4 [C0 33 00 01 80 01 00 00 00 78 00 04 C0 A8 B2 3C], unsupported resource records class (Resource temporarily unavailable)
2016:05:20-13:01:42 utm-server afcd[27428]: vy_plugin: E: failed to parse DNS RR in answer section of length 28 at offset 4 [C0 33 00 1C 80 01 00 00 00 78 00 10 FE 80 00 00 00 00 00 00 55 A6 D1 DD CB 2D CC 98], unsupported resource records class (Resource temporarily unavailable)
2016:05:20-13:01:42 utm-server afcd[27428]: vy_plugin: E: failed to parse DNS RR in additional section of length 18 at offset 4 [C0 0C 00 2F 80 01 00 00 00 78 00 06 C0 0C 00 02 00 08], unsupported resource records class (Resource temporarily unavailable)

I think this all started with the upgrade to UTM version 9.402-7.
Is someone experiancing the same issues?
