SharePoint’s Memory Leak

By Cory

Todd Carter over at todd-carter.com has posted his very in-depth findings regarding a pretty significant memory leak in SharePoint 2007. The problem lies around the HttpApplication object and ultimately around the SPHttpApplication object.

For each HttpApplication which is leaked a potential huge number of child references are too rooted and therefore leaked.

The memory leak has proven to be pretty significant for certain clients as you can see below…

After having the customer install the fix I have described here the process which would normally grow to 10 GB an hour and recycle never went above 2.5 GB! And even after taking all servers out of the load balancer and running the entire farm off one WFE the memory never went above 3.3 GB!!

Urgent Issue with SharePoint Service Pack 2

By Cory

Microsoft has released an important news announcement regarding a bug with Service Pack 2 that causes the software to go into trial mode that will expire in 180 days after the service pack was installed. There is currently no hotfix for the problem and the best way to solve this issue is to go into SharePoint Central Administration and re-enter your product key.

At this point we are still recommending that customers upgrade to SP2 but to ensure that after their upgrade they re-enter the product key and ensure that the product is no longer in trial mode.

Read more at the SharePoint team blog and follow the detailed steps to re-enter your product key.
