[Bug 907161] [NEW] BIND9 server lockup

[Tomas Targownik]

Public bug reported:

Bind9 process freezes once/twice daily. Process is still present but will not respond to any queries. The process will not gracefully shut down, requires 'kill -9' in order to stop it. Restarting the process restores normal operation.
Problem first occurred after upgrading from bind9 version 9.7.0.dfsg.P1-1ubuntu0.3 to version 9.7.0.dfsg.P1-1ubuntu0.4.

Problem seems identical to-
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=601830
and
https://www.isc.org/software/bind/advisories/cve-2011-0414

Tried the "-n1" workaround as described in the above ISC web page, but
the problem still occurs.

Resolved the issue by downgrading to bind9 package version
9.7.0.dfsg.P1-1.
