Hello List, I'm running a few BIND servers, but lately one of my servers suddenly starts responding to clients with servfail for every request from the clients, and BIND doesn't respond to the rndc or statistics interface anymore.
My logs for client-channel show me this: 25-Apr-2020 21:52:04.501 client @XX XX.37#2921 (google.dk<http://google.dk/>): no more recursive clients (1000/900/1000): quota reached I've removed all the dns traffic from the server, and the quota is still reached after 6+ hours? Do you guys have some clue what all this is about? - Or any suggestions where to look for any further information? I'm running BIND 9.16.1 on CentOS 7: named -V BIND 9.16.1 (Stable Release) <id:d497c32> running on Linux x86_64 3.10.0-1062.el7.x86_64 #1 SMP Wed Aug 7 18:08:02 UTC 2019 built by make with '--build=x86_64-redhat-linux-gnu' '--host=x86_64-redhat-linux-gnu' '--program-prefix=' '--disable-dependency-tracking' '--prefix=/opt/isc/isc-bind/root/usr' '--exec-prefix=/opt/isc/isc-bind/root/usr' '--bindir=/opt/isc/isc-bind/root/usr/bin' '--sbindir=/opt/isc/isc-bind/root/usr/sbin' '--sysconfdir=/etc/opt/isc/isc-bind' '--datadir=/opt/isc/isc-bind/root/usr/share' '--includedir=/opt/isc/isc-bind/root/usr/include' '--libdir=/opt/isc/isc-bind/root/usr/lib64' '--libexecdir=/opt/isc/isc-bind/root/usr/libexec' '--localstatedir=/var/opt/isc/isc-bind' '--sharedstatedir=/var/opt/isc/isc-bind/lib' '--mandir=/opt/isc/isc-bind/root/usr/share/man' '--infodir=/opt/isc/isc-bind/root/usr/share/info' '--disable-static' '--enable-dnstap' '--with-pic' '--with-gssapi' '--with-json-c' '--with-libtool' '--with-libxml2' '--without-lmdb' '--with-docbook-xsl=/usr/share/sgml/docbook/xsl-stylesheets' '--with-python' 'build_alias=x86_64-redhat-linux-gnu' 'host_alias=x86_64-redhat-linux-gnu' 'CFLAGS=-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic' 'LDFLAGS= -L/opt/isc/isc-bind/root/usr/lib64' 'PKG_CONFIG_PATH=:/opt/isc/isc-bind/root/usr/lib64/pkgconfig:/opt/isc/isc-bind/root/usr/share/pkgconfig' compiled by GCC 4.8.5 20150623 (Red Hat 4.8.5-39) compiled with OpenSSL version: OpenSSL 1.0.2k-fips 26 Jan 2017 linked to OpenSSL version: OpenSSL 1.0.2k-fips 26 Jan 2017 compiled with libxml2 version: 2.9.1 linked to libxml2 version: 20901 compiled with json-c version: 0.11 linked to json-c version: 0.11 compiled with zlib version: 1.2.7 linked to zlib version: 1.2.7 compiled with protobuf-c version: 1.3.2 linked to protobuf-c version: 1.3.2 threads support is enabled /Søren
