I am install pdns_recursor on Centos 6.5 32-bit from EPEL repo. The configuration is mostly default. I run the test from a Spirent testcenter and set max query rate to 5000 qps. The testcenter report about 10-20% unsuccessful query therefore I capture the packet and see that the response packet is missing Answer RR section. Run the same test again BIND on the same server does not have that phenomenon.
