There is some interesting new information about SharePoint eating up memory. Take a look at the details in the post SharePoint’s Sasquatch Memory Leak over at Todd Carters blog.
The evil seems to be many HttpApplications, which are not disposed properly. So every request creates a new HttpApplication, which eats up our memory at the FE servers.
And by the way, it does not mean we don’t have to get rid of our SharePoint objects as well :-)
So What is The Fix?
As of today we have just begun the process of having this issue addressed by the SharePoint 2007 servicing team so we do not have a fix at the time this blog was published. Once the fix is available I strongly advise everyone to install it and if implemented remove the workaround I provide below.
