<pre>Thanks Bill for the answer !<br><br>In fact, my application is working well with webrick and also with a single mongrel instance lunched via<br>the command : mongrel_rails start<br><br>When I check what is the difference in the gem loaded in both cases (mongrel_rails start and 
<br>mongrel_rails cluster::start) it seems that mongrel_rails cluster::start does not load all the gems that the first command is loading.<br>So I think it&#39;s related to the rails load environment, but I don&#39;t know how this environment is not loaded in the case of mongrel_rails cluster::start
<br>but loaded with mongrel_rails start.<br><br>Do you have any idea on why mongrel_rails cluster::start is not loading the environment ? I checked the path for the rails application ans it&#39;s ok <br>Is there any other alternative to force mongrel_rails cluster::start to load the rails environment ? 
<br><br><br>Cheers,<br><br>Addame<br><br><br>&nbsp;<br>Two things I would check:<br><br>1) Make sure you that you are not missing any gems that your  <br>application uses;<br>2) Check to see if your application will run under webrick
