Which setting in the Ivy-Server is relevant to increase the timeout?</p> <p>Due to the fact that we are able to customize error-messages from &gt; 5.1 we need to increase this (<a href="http://developer.axonivy.com/doc/latest/EngineGuideHtml/configuration.html#configuration-errorhandling">see here</a>).</p> <p>I've two settings in mind:</p> <ul> <li>connectionTimeout</li> <li>keepAliveTimeout</li> </ul>enFri, 27 Feb 2015 12:10:22 -0500https://answers.axonivy.com/questions/1181/which-setting-is-relevant-for-avoiding-dialog-instance-with-id-is-not-available-any-more/1182<p>The main reason for this error is a timed-out session. This timeout can be configured in the web.xml.
