Hi,
After a couple of hours, performance of bind 9.6.1 suddenly drops. While the server remains responsive, the response time increases, the rate of the failed queries increases, and CPU/load average usage increases. Restarting named solves the problem. I cannot find anything useful in the logs, but a quick search in this mailing list archive shows that other users reported somewhat similar problems with this version of BIND :( The operating system is Linux (Linux ns1 2.6.18-128.el5 #1 SMP Wed Dec 17 11:41:38 EST 2008 x86_64 x86_64 x86_64 GNU/Linux) , Red Hat Enterprise Linux Server release 5.3 (Tikanga). Output of named -V: BIND 9.6.1 built with '--enable-threads' '--enable-largefile' '--prefix=/usr/local' /usr/local/sbin/named: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, not stripped It is important to state that we just upgraded from 9.4.3-P2. Any ideas?
