copied!<p>A stack overflow occurs when your stack size reaches the defined limit and no more elements can be placed on the stack. The default stack size in Windows is normally 1 MB and has nothing to do with the total memory available to a process (therefore looking at the memory used by w3wp.exe makes not much sense in your case).</p> <p>It is possible to increase the stack size of an executable. From a Visual Studio command prompt you can issue</p> <pre><code>editbin /STACK:4000000 w3wp.exe </code></pre> <p>to increase the stack size to 4 MB.</p> <p>However, it could also be the case that the stack overflow is caused by a problem in the code (typically an <strong>infinite recursion</strong>) which would only occur when hosted as a WCF service.</p> <p>To trace this problem down, you need to find out where the recursion occurs. If you can't get a stack trace intensive logging will help you here.</p> <p><strong>UPDATE</strong></p> <p>As it seems, w3wp.exe does not use Window's default stack size of 1 MB but uses only 256 kB (see also this <a href="http://support.microsoft.com/kb/932909" rel="nofollow noreferrer">knowledge base article</a>):</p> <pre><code>dumpbin /HEADERS c:\windows\system32\inetsrv\w3wp.exe </code></pre> <p>prints: </p> <blockquote> <pre><code>[...] OPTIONAL HEADER VALUES [...] 40000 size of stack reserve </code></pre> </blockquote> <p>A <a href="http://blogs.msdn.com/tom/archive/2008/03/31/stack-sizes-in-iis-affects-asp-net.aspx" rel="nofollow noreferrer">blog post</a> suggest to patch w3wp.exe using <code>editbin</code> as described above.</p>
