POWhy would a WCF webservice hosted in IIS randomly stop responding?
text
Body
copied!<p>This is my first attempt to use WCF so there may be something fundamentally wrong with this approach - if so I'm happy to switch to a different model. At quick glance, I thought the answer to <a href="https://stackoverflow.com/questions/739312/c-wcf-wcf-stops-responding-after-about-10-or-so-calls-throttling">this question</a> would have worked, but my scenario appears to be different.</p> <p>I have an ASP.NET MVC website where the controllers access the WCF client class through an intermediate repository. The repository is just a wrapper around the WCF client that instantiates it once and sets the proper endpoint address.</p> <pre><code>public class WcfRepository : IRepository { private MyWCFServiceClient client; public WcfRepository() { client = new MyWCFServiceClient(); } public bool MyMethod1() { return client.MyMethod1(); } ... etc } </code></pre> <p>I can access different pages on the website until a seemingly random point where the WCF service will start timing out. It doesn't matter which method I call either - it timesout on different ones. I cannot see any exceptions on the IIS machine hosting the WCF service either; the event log there is empty. A simple method like <code>GetCustomerByName()</code> which worked two minutes earlier will no longer so I think it's more to do with WCF communication rather than the service itself.</p> <p>If I try to use the WCF Test Client after one of these timeouts occurs, it will also fail. But, if I wait a while (and choose 'start a new proxy') then things will work again.</p> <p>I'm very confused - should I be creating a new instance of the WCF client each time I want to use it in my repository? Is there another way I should be using the client? Wrapping each call in <code>Open()/Close()</code> doesn't work either since the first call to <code>Close()</code> puts the object in a disposed state.</p>
