I would like to know the following personnel, an enterprise application has a large number of sessions in manager of Tomcat .
The system has been increasing in the number of users and I would like to know tips from colleagues of forum what I could do to see what has caused the number of sessions to rise and lock the system, causing it to become a stop and start in the manager and then make a shutdown and startup via terminal.
The Java application was developed using Java 7 , JSF , Spring for dependency injection, Hibernate among others.
Thank you
