I'm trying to test unbound witk dnstap. It works fine with low load, but 
exists with segfault at high load. The segfault only happens when dnstap 
is enabled in configuration.

I am using the debian package (version 1.5.3) avaible in [1] and 
recompiled with dnstap enabled.
I'm following instruction descripted in [2] and using fstrm version 

To test the server, I'm using dnsblast [3] with the follow command:

./dnsblast <server address> 50000 500
