Issue with ASP.Net application locking up on some users
Posted on 2012-09-01
I'm not sure if I'm going to find an answer here, but I'm looking everywhere trying to solve this problem.
I have an ASP.Net web application (3.5, Visual Studio 2008, C#, SQL Server 2005 database backend). I have the website deployed to a production server (Windows Server 2008). I have users all over the country that log in and manage their data (user profiles, form submission, basic stuff). I'm also using Membership to manage users and permissions. The problem is that I have a few users reproting that when they get to a certain point the application freezes or locks up on them. They have to kill their browser and start over, usually ending with them not getting their data in. The browser in most use is IE8. My first thought was network issues, but I'm trying to see if it's something in my application. I have no control over the network. I do use a lot of DevExpress controls in the application, primarily gridviews and panels. It appears that most of the problems come from a few forms where I use these controls. I used them e a lot early in the develpment process to speed of the work, but now I'm wondering if they are more trouble than they're worth. Could the controls be the source of my problem, or am I missing something else? I have never had any problems with them, nor have I seen any from people who are in close proximity (same building). The only people reporting them are people spread out over the country. Any ideas on what other ideas I can look into woul be greatly appreciated.
