First I don't really know my way around DBs (I'm just the "guy good with computers" around here) so if I'm making some sort of newbie mistake, please bear with me. So there's an accounting program that we use at work and suddenly the PC where it's installed filled up its 500GB HDD Looking around I saw that the folder C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\LOG was the culprit as it had >500,000 files (explorer crashed when I tried to open it, had to use the command line). So I deleted the files but after checking again after a week I find that the folder has again grown to 12GB, so I set to try and discover the problem. Now the actual problem is that a single database used by the program is generating several SQLdump files per minute just by being open. The weird thing is that the accounting program has 5 similar databases (one for each account) and that single one has this problem. The tools at hand: MS SQL Server Manager Studio Express Things I've tried: - Setting AutoClose to False - Setting Recovery mode to Normal - Backing up the DB, deleting and restoring Nothing seems to stop the barrage of files being created. Pics: Highlighted: file number and size, the DB involved Highlighted: DB opened (just opened, no transaction has taken place), several files had been created in just 10 seconds. Thank you for any input.
