Exception of type 'System.OutOfMemoryException' was - Sitefinity - Bugs & Issues

There's another thread that talks about this problem, but it seems to have run dead so I'd like to bring this up again.

This morning we were working on our Sitefinity site, on the master pages in particular. We were struggling to disable the CSS files rendered out by the Telerik controls, but we eventually figured it out.
Then we moved our theme files into the new folder structure under App_data as suggested by Telerik. We followed the instructions to configure the new theme under the administration section, created a new template and applied the new theme to the template.

Everything worked well, but then suddenly the application started crashing. We monitored the server memory and noticed a serious problem with the worker process memory consumption. From the rate at which it swallows up memory (up to 2Gb within 5-10 seconds) it would seem like some kind of infinite loop. What doesn't make sense though is why?

The Sitefinity and Windows event log list the following:

We've restarted the Windows 2008 server, which didn't help.

Right now, the application is broken, we can do nothing about it. Everything we've tried has failed. Not sure what else to do.

Anyone find a solution for this yet?

Have you made any changes in your templates especially the navigation menu ?

If we go to the backoffice, the navigation widget can"t find top level page... It appear empty even if we delete and recreate it.. When we launch our page we get this OutOfMemory error...

We have sitefinity 4.4

Hi,

The problem is usually caused by several things. The most possible one is because there is a page template using a master page based on itself. Can you review Design->Page Templates and check the column base on template and see if a template using a master page is based on itself. For example a template is using Page.master to create a template called MyTemplate and MyTemplate is based on a template called MyTemplate. This is causing a loop because MyTempalte is searching for MyTemplate which is also searching for MyTemplate and so on and this fills up all the server memory and the error is thrown.

Another cause is if you are using a custom navigation widget on some of the pages and in the code behind of the control IsNodeAccessible property is used. This is not working properly in Sitefinity 4.2 and above so it is best to remove it. It is also causing a loop.

Another cause is if using a widget that for example queries an image,document or video library and displays results on the frontend. Sitefinity API used for taking media content might be wrong and getting all images in the library and then fitering them to show only a few (App.WorkWith().Images().Get().ToList and then filter with .Where() ).

If the system is eating so much memory there is a memory leak most likely caused by some of the mentioned issues.

Hi Stanislav,

The duplicate template seems to have been the problem. It never occurred to me that even though the front end was bombing out within a few seconds that the back end would still work, but it did.

Thanks for the help.
