Hi,
I had a problem where ReportServerTempDB log kept growing even though it was in SIMPLE recovery model. On further investigation I found the column on sys.databases called logreusewaitdesc was set to LOG_BACKUP.
How can the log need backing up on a database that is in simple recovery model?
I put the database into FULL recovery model, performed a full backup and 2 subsequent log backups but the status did not change. I changed the recovery model back to SIMPLE and that put the log_reuse_wait_desc to NOTHING allowing me to reclaim disk space by shrinking the log. The transaction log on that database is no longer growing.
