How to fix WatiN OutOfMemoryException

Question

I'm iterating over a very large list of divs with WatiN (about 3000) and I'm getting the error:

A first chance exception of type 'System.OutOfMemoryException' occurred in WatiN.Core.dll
System.OutOfMemoryException: Insufficient memory to continue the execution of the program.
   at WatiN.Core.UtilityClasses.UtilityClass.TryFuncFailOver[T](DoFunc`1 func, Int32 numberOfRetries, Int32 sleepTime)
   at WatiN.Core.Native.InternetExplorer.IEElement.GetWithFailOver[T](DoFunc`1 func)
   at WatiN.Core.Native.InternetExplorer.IEElement.GetAttributeValue(String attributeName)
   at WatiN.Core.Element.GetAttributeValueImpl(String attributeName)
   at WatiN.Core.Component.GetAttributeValue(String attributeName)
   at WatiN.Core.Element.get_OuterHtml()
   at WatiN.Core.Document.get_Html()

When clicking a div then getting the html of the browser.

Does anyone know of how to fix the memory issue? I am hoping I can use a different function or split the page somehow. Perhaps I will need to use something other than WatiN

The code is:

 foreach (Div d in browser.Divs)
                    {

                        try
                        {
                            d.Click(); // click div

                            System.Threading.Thread.Sleep(250); //wait for new data to load

                            string url = "";
                            if (browser.Html.Contains("http://www.google.com/url?")) // check if an external link exists on the page - this causes the memory exception
                            {

Thanks for any help

Answer 1

In this case it was a problem with Internet Explorer as the amount of memory it used went beyond 1GB and presumably hitting the 32-bit .net object limit somewhere.

In my case running on a 64-bit system "fixed" (or rather, delayed) the issue.
