log message severity

[gagadget at free.fr]

Hi list,

Why the log messages :

general: info: zone toto.tata.fr/IN: refresh: non-authoritative answer from
master 10.xx.xx.xx#53 (source 0.0.0.0#0)

is in info severity in BIND 9.4.2 and was in notice in BIND 8.4.7 ?

We used to trap those messages to clean the zones deleted on master servers
managed by admin that don't inform us for deleted zone.

The problem is that if I configure the logging channel to be in "info" level,
the log file become very heavy.

Any help welcome.

Gael.
