Large number of writes can cause it. How often do you backup your transaction log? If you haven't done it for a while, it's time. To see your free space, simply go to EM and right click the database, click view ant then click Task Pad.
My database doesn't have any writes,But what i observed is that it's coz of sql server agent and its jobs. The log stopped to grow after i stopped sql server agent. Should it be because of backups or anything?
I am just taking a differential back of the database,Not taking any transactional backup.
Can anyone help in this issue?
