| Yes. By correctly rotating the file:
| 
| % cp /var/log/named.log /var/log/named.log.old
| % cp /dev/null /var/log/named.log

This may lose you a few log entries between the file copy and the
file reset (cp /dev/null), as BIND would still be writing to the old file

Better:

% mv /var/log/named.log /var/log/named.log.old
% ndc reload

This will rename the file, and BIND will be writing to the renamed
file until it gets the reload signal, which will make it properly
close and reopen the file. As the file does no loinger exist under the
configured name, it will create a new one and write to that.
