Hi Doron,

The following statement "This way the log file stays small and whenever a new process starts, the new batch will reuse the same log file space and it will not grow" from your article is misleading. It's only true if database is in Simple recovery mode or it's in Full recover mode and log backup is done between batches. And even then another transaction may prevent reusing previous batch log space.
