segfault

I have a big problem. I installed the bind9 nameserver to three different computer. two Ubuntu 10.04.4 LTS, and one Ubuntu 11.10

I compiled it 9.7.0, 9.7.3, 9.9.0 with this method:

./configure --prefix=/usr --sysconfdir=/etc/bind --localstatedir=/var \
--mandir=/usr/share/man --infodir=/usr/share/info \
--enable-threads --enable-largefile --with-libtool --enable-shared --enable-static \
--with-openssl=/usr --with-gssapi=/usr --with-gnu-ld \
--with-dlz-mysql=yes --with-dlz-bdb=no \
--with-dlz-filesystem=yes --with-geoip=/usr

make

make install

After the set up for dlz/mysql, the BIND server is working perfetctly until 5-30 minute long. Ahter i got segfault.

I resolve temporaly the problem with a simple process watchdog, and if the named is stopped, the watchdog is restart it, but this is not a good idea in long therm.

My log output is:
