This question already has an answer here:
I have a database that is set to Simple recovery mode. There is 99% free space in the log file and I can manually truncate the log file right down to 500 MB.
The next day, after a daily import process runs, the log file will be back up to ~70GB.
If I check
sys.databases it returns 0 which would indicate nothing is blocking a shrink operation.
Why isn't the log file naturally shrinking? Also, how can I find what SQL queries are causing the log file to grow to such a size?
