AbleCommerce Shopping Cart Software

I am currently running in development mode reconstructing my Able Commerce site bringing over data from an existing 5.5 version site, using built in tools in Gold (Importing & Exporting via a CSV file). I am receiving, on a fairly regular basis (daily) the below error message, which I am concerned about. I am running on IIS 7 using ASP.NET 4.0 Integrate Pipeline mode. If I recycle the App pool, it comes back. Any ideas? SQL Server 2008 R2. TIA!

Hi there,

Can you tell me which build of AbleCommerce you are using please? To confirm, this error appears in the storefront (any page), and you can get the site to work again by recycling the App pool?

Thanks,
Katie

Here is my Able Commerce version, and yes, I can get the site working again by recycling the app pool, but... I would rather not have to do that, obviously.

Let me check on this for you.

Thanks Katie. At this point, I cannot get the site to stay up for longer than an hour or two without receiving this message. I think there has been another version released and wondering if that would help?

For now, I am going to try to upgrade my server to MS .NET Framework 4.5.1 and see if that helps. Right now, I'm on .NET 4.0.

There must be some other issue. The site shouldn't be crashing so often, regardless of the .Net version. I'm wondering if there is a problem with the data that was imported. It would be helpful if we can figure out what pages are crashing. It's probably something specific that is causing this to happen.

I would think so too Katie. When the site crashes though, it's the whole site, from the home page on. Perhaps it is because of a piece of data that was imported. Maybe an invalid string of text or something? Over 3,000 products were imported that were worked on over the last 7 years by multiple people and Lord only knows what data may be causing an issue.

I upgraded .NET to 4.5 on the server last night and no crashes yet today, but we'll see... I'll continue to keep us posted.

Yes, please keep me updated. I have to wonder if there was a problem with the Net 4.0 installation. If some of your imported products had issues, I would expect errors on the product pages, but this seems more of a general (the site is not responding) issue. I hope the upgrade to .Net 4.5 continues to work for you.

Keeping this thread updated, in going to accesss our new AC Gold site, currently in development, the error once again surfaced. Again, a recycle of the application pool brought it back to life. Any ideas on how we can further pinpoint as to what's causing the error? We're pretty close to going live and want to make sure we're as stable as possible. I'm willing to do what it takes. Thanks Katie!

Let me check with the developers. I might have a fix for this. However, we do not know the exact reason the site is going down, but we should be able to recover from the situation and not require that you recycle the application manually.

It appears this problem is not going to go away on it's own. My customer reported the error again today. What can I do? How can I troubleshoot this? We are getting close to being launch ready and definitely don't want this error surfacing to customers.

You are running on
IIS 7 (Integrate Pipeline mode)
ASP.NET 4.0
SQL Server 2008 R2

Windows 7 or 8 ?

Do you have all the latest service packs and patches installed?

Do you have any customizations in Global.asax?

Do you have any custom HttpModules added?

This is not a fix, but it 'might' help bring the site back to life if it crashes.

Go to:
http://help.ablecommerce.com/upgrades/a ... s_gold.htm

Download the patch for:

AC8-2254
Store does not initialize if the database connection is lost
Fixed in \bin\CommerceBuilder.Licensing.dll

Please make a backup of the original file before replacing.

I think Katie is on the right track- we do see this happen at times, even on the home page where there is little "code" running, and I had thought the database connection might be the problem.

Katie, I posted a bug report on this - some of the hot patches in the link you sent are throwing a 404 error. See image below.
