Dave, This patch only would come into play if you were sending the linger command over the socket once connected. Before the patch, if you executed "linger" it would never disconnect the socket until you did it yourself from the client side. After the patch it should apply a default timeout of 600 seconds or allow you to specify a smaller one such as "linger 20" In any case this would be moot if you manually call the disconnect yourself before you close your script. Are you sure this patch is causing you problems? This really should go in a JIRA if so, at least re-open the existing one that added the patch and post your findings. Also the guy with the local mods to the java stuff, please contribute them and we can add them to tree. On Sat, Dec 17, 2011 at 6:26 AM, Dave May <Dave.May@patlive.com> wrote:
I experienced similar problems when load testing Plivo on the latest Git, but didn't feel like I had enough data gathered for a "proper" report. After each call, the remote ESL socket would be left in a CLOSE_WAIT state. ****

I think the problem started on December 8th, with the resolution of this Jira:****

When I rolled the code back to the revision just prior to this change, my problems went away.****

** **
Hi,****
****
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. ****
****
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?****
****
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.****
