1. This can be caused by multilingual templates on the site. It is possible that some overlapping language templates might be causing the issue.
A template might causing an internal loop which fills the memory of the server thus throwing an exception. Please check if you have any layout controls that might be causing the issue or if you have applied other changes to the masterpage that you use for your pages that are throwing the error.
Resolving this will include examining the template that a problematic page uses and its layout controls, making changes to the layout controls or removing and then adding new language version to page template might resolve it. Excuse me for the resolution that is not focused on simple steps, but the random issue acts unpredictable and there are many factors that take part in its cause.

2. In the project you sent me I used only the modules because I was not able to run SitefinityWebApp. Can you send SitefinityWebApp that I can add to visual studio and examine the problem?
All the best,
