If not, select those columns to be viewed (Task Manager choose View->Select Columns... Then run your app and take a look at those columns for that app and see if one of those is growing really large.

Posted on 2008-08-26 .NET Programming Visual Basic.NET 1 Verified Solution 6 Comments 1,790 Views Last Modified: 2013-11-07 Hi, I have an application written in VS 2005 (VB). users of the application (about 300) run error creating it from their own laptops or home computers so I have no control over the environment it used in. The architecture is as following: MDI parent is loaded maximized and loading one of the child form (maximized ). other forms are loading based on users choice in main menu.\ Now the issue. One of the form RANDOMLY fails to load throwing exception (see the question title and in attached Snippet) The form initialization error creating window goes fine but whenever form.show method called the exception is thrown I did a lot of research on this matter just to find out that this is kind of generic exception that totaly irelevant to memory. I am unable to reproduce this error on my workstation. it happens for random people at random time. I have seen it happened in Win XP Home and Vista Home Premium - never seen on XP pro (if this matter) the schedule is the main form the users work with so usually they try to open it right away when the application is loaded. On the form there is databound grid and I am using background worker objects to load / refresh data on the grid. If someone need full source of the for, let me know. there are other forms build similar to this one but i never saw this error happen to them Any help will be greatly appreciated.
