If you have created 1000 or more aggregations and show a view with many hosts or services than you could get massive performance and memory problems in your Apache process. The reason is the computation of the BI icon in the drop down menus of hosts and services. This was only done in order to check the visibility of the menu itself. The menu is now always visible and thus the computation is not longer neccessary.
