That's how BIND implements DDNS. The .log file is a transaction log of
changes that have been made to the zone as a result of update requests.
Every so often, the name server writes out a new copy of the dynamic
zone and deletes this transaction file. The .log file is created so
that if the name server crashes, it can re-create the up to date
version of the zone from the (old) zone file and the transaction log
file: ie it's a roll-forward operation. When the update request is
done, the in-core copy of the zone is modified. The .log file just
provides stable storage for that update until a fresh zone file
containing the new version of the zone is written out.

I hope you realise the security and scaling problems you get from
DDNS. At the very least, you should be using TSIG authentication =>
running BIND 8.2.2P5.
