Running in Debug Mode  When you re developing and debugging an application  you will typically run with the debug attribute in the web config file set to true and your DLLs compiled in debug mode  However  before you deploy your application to test or to production  you should compile your components in release mode and set the debug attribute to false   ASP NET works differently on many levels when running in debug mode  In fact  when you are running in debug mode  the GC will allow your objects to remain alive longer  until the end of the scope  so you will always see higher memory usage when running in debug mode   Another often unrealized side-effect of running in debug mode is that client scripts served via the webresource axd and scriptresource axd handlers will not be cached  That means that each client request will have to download any scripts  such as ASP NET AJAX scripts  instead of taking advantage of client-side caching  This can lead to a substantial performance hit   Source  http   blogs iis net webtopics archive 2009 05 22 troubleshooting-system-outofmemoryexceptions-in-asp-net aspx

This problem usually occurs when some process such as loading huge data to memory stream and your system memory is not capable of storing so much of data  Try clearing temp folder by giving the command       start -  run -   temp
