This indicates connectivity problems between the system running Guacamole Client (Tomcat) and the system running the database that you're using. If they running on the same system this could indicate that the database had crashed. If you're running the database and Tomcat on different systems then it could indicate a connectivity problem between the systems.
Also, my section is connecting out. In guacamole properties i have put time
out connection for 60 minutes and asking for login again. Please help me.
What property did you set, what value did root specify, and how long is it taking to time out?
