You create an event receiver. The ItemAdded method for the event receiver contains the following code segment. (Line numbers are included for reference only.) 01 SPWeb recWeb = properties.Web; 03 { 04 using (SPWeb web = siteCollection.OpenWeb()) 05 { 06 PublishingWeb oWeb = PublishingWeb.GetPublishingWeb(web); 07 PublishingWebCollection pubWebs = oWeb.GetPublishingWebs(); 08 foreach (PublishingWeb iWeb in pubWebs) 09 { 10 try 11 { 12 SPFile page = web.GetFile("/Pages/default.aspx"); 13 SPLimitedWebPartManager wpManager = page.GetLimitedWebPartManager (PersonalizationScope.Shared); 14 } 15 finally 16 { 17 if (iWeb != null) 18 { 19 iWeb.Close(); 20 } 21 } 22 } 23 } 24 } You need to prevent the event receiver from causing memory leaks.
