SQL Server Memory Log

Hi,

I am observing one of our production server for last 1 month. The memory utilization of server is increasing by 10% every week and it seems to reach 100% by couple of weeks. This is also being observed that the number of users are also not high on system.

My concern is how to find which particular process or query or job is hiking the memory.

This is what I have now.



Any help and suggestion is appreciated.

Thanks
