Build bind with its internal memory allocator. To to do this, change
CONFIGURE_ARGS in /usr/ports/dns/bind9/Makefile to read like:
--
CONFIGURE_ARGS= --localstatedir=/var --disable-linux-caps \
--with-randomdev=/dev/random \
STD_CDEFINES=-DISC_MEM_USE_INTERNAL_MALLOC=1
--
make clean
make WITH_PORT_REPLACES_BASE_BIND9=YES
make install
/etc/sysctl.conf settings:
net.inet.raw.recvspace=128000
net.inet.udp.recvspace=256000
net.inet.tcp.sendspace=128000
net.inet.tcp.recvspace=128000
net.inet.tcp.inflight_enable=1
kern.ipc.maxsockbuf=256000
kern.ipc.somaxconn=2048
