Bind9 Log data consistency

Hello,

Configuration:

Bind9 configured to write logs into sys/rsyslog. - From there, data is getting 
phrased and used for analytical / billing purposes.

Scenario:

At some point, a problem arise and rsyslog crashes for any possible reason. 
There is no unix logging socket any more bind can communicate with.

Bind seems to have behaviour of ignoring this error and it continue with 
normal operation - although no records are kept pointing to any transactions 
happening on the system since the moment of last crash.

Is it possible to somehow configure bind to treat those errors as fatal. For 
example - abort execution because socket cannot be opened, log files written, 
and so on.

Or, is there any other solution to prevent possibility of answering DNS 
queries without logs being stored and achieve full consistency between events 
and logs.

Thanks & Regards,
