Hey André, > According to vmtools the server is boring most times..

According to Tomcat Configuration Reference 5.5 : connectionLinger The number of milliseconds during which the sockets used by this Connector will linger when they are closed. The default value is -1 (socket linger is disabled). According to Tomcat Configuration Reference 7.0.37 : connectionLinger The number of seconds during which the sockets used by this Connector will linger when they are closed. If not specified, the JVM default will be used. As I'm at 7.0.37 I have to figure out where an how to set linger options at the JVM. > I'll have a look. thx --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
