Hello dear Reader,
I have a problem with a log-File of only one database at one of our customers.
Since a few weeks the .ldf file grows over the day to 250 Gigabyte (while the .mdf file size is around 5 Gigabyte).
I took a look in the logs.
-Recovery Model is Full.
-Transactions-Logs are saved.
-The .ldf-File is 90% full (disk usage report).
-The .ldf-File gets shrinks each day after saving the data smaller to a few megabytes and grows in minutes till hours each day to 250 Gigabyte. (disk usage report)
-I should add that there are no open transactions!
-The database only gets used by a third-party application.
How I can find out / Monitor why the log file shrink and grows every day by ~250 Gigabyte?
It seems really that the transactions are valid (they get successfully cleaned each day, transactions saved but still 90% of that 250 Gigabyte are in use).
