[knot-dns-users] Crashing Knot 1.0.1

Hi: I'm trying to test Knot 1.0.1 with a basic configuration, and I managed to crash it. Compiled from source on a Ubuntu 11.04, serving one signed zone. uname -a Linux turista 2.6.38-13-generic-pae #55-Ubuntu SMP Tue Jan 24 15:54:51 UTC 2012 i686 i686 i386 GNU/Linux autoreconf -if ./configure --prefix=/opt/knot make sudo make install The configuration file looks like this system { identity "knot 1.0.1"; storage "/opt/knot/var/knot"; } interfaces { my-iface { address 192.168.22.152@53; } } zones { co.nz { file "/opt/knot/etc/co.nz"; } } log { syslog { any warning, error; } } Then root@turista:/opt/knot# sbin/knotc -c etc/knot.conf compile Parsing file '/opt/knot/etc/co.nz', origin 'co.nz.' ... Compilation successful. root@turista:/opt/knot# sbin/knotc -c etc/knot.conf -i start control: Running in interactive mode. Reading configuration '/opt/knot/etc/knot.conf' ... And when I send a query to the server dig dnskey co.nz @192.168.22.152 I get this in syslog Mar 15 17:00:44 turista kernel: [1487877.778230] knotd[6010]: segfault at 0 ip (null) sp b489e03c error 14 in knotd[8048000+50000] The error is consistent. If I restart the server, wait a little bit to load, and then send the query, it crashes. Running under gdb provides the following backtrace (gdb) bt #0 0x00000000 in ??

Unfortunately I can't send you the zone. Cheers, -- Sebastian Castro DNS Specialist .nz Registry Services (New Zealand Domain Name Registry Limited) desk: +64 4 495 2337 mobile: +64 21 400535
