</div></div><p class="MsoNormal"> </p><p class="MsoNormal">Hi,</p><p class="MsoNormal"> </p><p class="MsoNormal">I built a web application that connects to Freeswitch using the org.freeswitch.esl.client.Client. I connect the Client object from a Spring annotated service that I call from a Spring controller. I put the connected client in my ServletContext, so I can access it later to call client.cancelEventSubscriptions() and client.close() from my ServletContextListener contextDestroyed method when Tomcat is shutting down.</p>
<p class="MsoNormal"> </p><p class="MsoNormal">The problem I'm having is that even after I call close on the client, there are still a bunch of active threads that the client has spawned in the background. These threads are causing Tomcat to hang when I'm shutting down. Can anyone suggest an approach that would enable my application to disconnect the Freeswitch client when Tomcat is shutting down that would allow Tomcat to shutdown gracefully?</p>
<p class="MsoNormal"> </p><p class="MsoNormal">Below are errors from my Tomcat log for the threads that I have identified as being related to the Freeswitch client. I don't know how I can get to these threads to interrupt them and Client.close() seems to leave them hanging.</p>
