There is limitation on how any open file handles (this includes sockets too) OS can support. If this limit is reached, you get above exception. If you are on ∗ nix OS, this can be easily increased.
Open /etc/security/limits.conf
I am on Ubuntu so for me I just execute following command from command line
sudo gedit /etc/security/limits.conf
and add following two lines
∗ soft nofile 3072
∗ hard nofile 3072
Save and Close the file. I don't know how to load these settings from command prompt but rebooting did the trick. To make sure these changes are done execute
ulimit -n
If you know how to do it on windows please add comment.
Thanks.

Mobicents JAIN SLEE Server 2.x unites in league of JOPR Console!
JBoss Operations Network (JOPR) is becoming the de-facto for managing suite of JBoss products and rightly so as it provides administration, monitoring, alerting, operational control and configuration in an enterprise setting with fine-grained security and an advanced extension model.
Since Mobicents Sip Servlets Server is already having JOPR agent and we have experienced how easy it becomes when it comes to management using JOPR JAIN SLEE server team also decided to venture on JOPR so all the products of Mobicents have same look and feel and can be managed from same Console.
Big thanks goes to JOPR team for answering all the queries that really saved lot of time had we tried to solve them by ourselves.
The features of Mobicents JSLEE (version 2.x.y) JOPR is in-line with Mobicents Management Console that is available with Mobicents JSLEE Server 1.x.y.
The JOPR Agent (binary) for Mobicents JSLEE will soon be available with release Mobicents JAIN SLEE Server version 2.0.0CR1. However if you are getting little impatient and want to give it a try right away, download the source code from mobicents svn and call 'mvn clean install'. You should see the agent jar at jopr-plugin/target/mobicents-slee-jopr-as-5-plugin-2.0.0-SNAPSHOT.jar
The Agent is built using the source RHQ 1.4.x trunk.
The first binary release of RHQ 1.4.0.b01 server can be downloaded from here. Follow the blog from Heiko to know more about this release.
Unzip rhq-server-1.4.0.B01.zip and start the server from 'rhq-server-1.4.0.B01/bin' using 'rhq-server.sh start'. Once server is started visit http://localhost:7080/. First time it will ask for configuring the Database and for test you can simply select the HSQLDB. To know more about installation of JOPR have a look at http://community.jboss.org/wiki/jopr-installation.
You also need to have JOPR Agent, I found one in rhq-server-1.4.0.B01/jbossas/server/default/deploy/rhq.ear/rhq-downloads/rhq-agent/rhq-enterprise-agent-1.4.0.B01.jar. Unjar it and start the Agent from 'rhq-enterprise-agent-1.4.0.B01/rhq-agent/bin' by executing 'rhq-agent.sh -l' (-l argument is only for first time to configure the agent, the subsequent starts can be done by executing command 'rhq-agent.sh'). It will ask few questions for configuring agent and has default answers for each, just press 'enter' for each.
To install the Mobicents JAIN SLEE JOPR Plugin using Jopr UI, go to Administration → System Configuration → Plugins. On the Agent Plugins tab (selected by default), on the bottom of the page, click on Add..., browse to the Jopr plugin JAR file and select it. Finally, click on the Upload button and the plugin will be deployed. Click on Scan for Updates and it should be shown in the list as "Mobicents JSLEE Server 2.x". On the Agent Console call 'Plugins Update'.
This will deploy the Plugin on Agent side and it will automatically discover your Mobicents JAIN SLEE Server 2.x.y. To add mobicents server to RHQ Server go to Overview → Auto Discovery Queue on server page and Import Mobicents JAIN SLEE Server. If you don't see an entry like 'Mobicents JAIN SLEE Server 2.x.y (:port) something went wrong and check necessary logs of server and agent.
Voilà! You have JOPR monitoring your Mobicents JAIN SLEE Server and it should look something like this
If you want to know more about how to manage JAIN SLEE Server, build the docs by calling 'mvn clean install' from /jopr-plugin/docs and browse the docs.
Enjoy the new shiny management console!
