There\'s no other option actually.
Have you tried the uri
http://localhost:8080/OpenKM/repository_users.jsp ? on community version this might runs.
About this isssue. OpenKM only enables one user session active for security purposes, really it\'s something like a jboss session, but because UI is ajax and user can be so much time with opened browser without doing any action ... there\'s some system to mantaining this connection keep alive, for this reason when you close browser, your session continues hanging during 30 minutes, because we made some extra control from jboss sessions.
system menu options are to prevent when - normal users - not exits openkm and hangs sessions. There\'s no way to prevent system user bad uses ( I don\'t know if you understand me )
The other option you\'re suggesting, restarting jboss, obviously on a production environment is not desireable.
