We have in house linux servers from different vendors, so each server has a different distro ( rhel, centos, debian, ubuntu ) and tomcat or jboss.With some web application,  if the logged user ( windows client ) doesn't touch the web pages, after a few minutes her session is lost.So she has to redo the application login. The vendors say that from the web apps view, the session timeout is high ( like 30 or 60 minutes of inactivity ).are there specific tomcat / jboss session expiration ?could be some tcpip settings, like tcp_keepalive_* or tcp_retries2 ?We have about 50 offices locations, but to start we are investigating these problems only on the building with the servers : clients and servers are on the same ethernet and same ip network, all copper wired, only a few 100 Mbps switches.best regards, Sala
