The GeoHelm home page contains button contorls for starting, stopping, and restarting Tomcat
We strongly recommending using Stop followed by Start over use of Restart.
While Restart should perform a clean shutown and startup, if there are issues with your configuration the Restart is more likely to spawn multiple sessions.
To restart Tomcat:
You can, of course, start and stop and restart Tomcat via the command line as well.
If you recieve an error message when starting or stopping Tomcat, see Troubleshooting Tomcat.
