Sorry, I also meant to show how the forwarding is configured:
-----
forward first;
forwarders { 192.168.122.1; };
allow-query { localhost; 192.168.122.0/24; };

Created attachment 324893 [details] b2zipped core file Description of problem: host(1) segfaults for me when asking about certain servers, right before it should output MX records: [root@ipa-server local]# host redhat.com redhat.com has address 209.132.177.50 Segmentation fault This is a virtual machine, using libvirt's NAT network config. I have bind running on that machine that provides DNS for my virtual machines, unknown requests are forwarded to libvirt's default DNS: ---- ---- AFAIK the segfault occurs only for requests from outside - i.e. when the local bind forwards the request. Version-Release number of selected component (if applicable): bind-utils-9.5.0-35.P2.fc9.i386 How reproducible: not always, but often enough. Steps to Reproduce: 1. host redhat.com Actual results: segfault Expected results: no segfault Additional info: core file attached. gdb session: (gdb) r redhat.com Starting program: /usr/bin/host redhat.com [Thread debugging using libthread_db enabled] [New Thread 0xb8028b00 (LWP 2186)] [New Thread 0xb7fe5b90 (LWP 2189)] [New Thread 0xb75e4b90 (LWP 2190)] [New Thread 0xb6be3b90 (LWP 2191)] redhat.com has address 209.132.177.50 Program received signal SIGSEGV, Segmentation fault.
