The most important piece of this application uses an AJAX function to send HTTP requests to the JBOSS/Tomcat every 0.9 seconds. We should have around of 100 users logged 8 hours per day sending requests every .9 secs. I believe that something is building up, and after some load (3 days) it just stop to respond HTTP requests. So far its only a theory... I couldn't find a final solution. My partial solution is restart the JBOSS every night. Thank you once again.
