Exception of type System.OutOfMemoryException was thrown

Exception of type 'System.OutOfMemoryException' was thrown

Description: An unhandled exception has occured during the execution of the current web request.Please review the current stack trace for more information about the error and where it originated in the code.
If you have host your site in shared web hosting, than one reason of occurence of this type of error might due to IIS and in situations where the server is under a heavy load, IIS reset might solve this issue but if hosting provider will not allow to manage IIS than we can forcefully restart IIS by recycling of APPDomain.
In Asp.net ,
When the application domain is unloaded , the next request that comes in all assemblies need to be reloaded, the code has to be re-jitted and the cache including any in-proc session variables etc. are empty.
An application domain will unload when any one of the following occurs:
Machine.Config, Web.Config or Global.asax are modified

so, changes in any of the above file might solve this Exception issue.
Hope this helps.
