As most of you know, the OWSTimer memory leak is still an issue with SharePoint 2010. I created a scheduled task to run using PowerShell to stop the process nightly. Here are the instructions to create the scheduled task.
Open up your Windows Task Scheduler and right-click on Task Scheduler Library and then choose “Create Task” to start the Create Task panel.
Note: If you don’t know where the task scheduler is either search for it or type %windir%\system32\taskschd.msc /s in your Windows start menu search bar.
