Service Desk SQL database growing out of control

Service Desk SQL database growing out of control

Hi,
We have service desk running on  9.1  Build  9118 with a SQL db running on another server. The database started on 20GB a couple of weeks ago, its now on 70GB.
Java.exe process is using all the memory on the server where the service desk is installed.
Any ideas?
Thanks
