Crash is a complementary tool for development and maintenance. As it opens telnet and SSH sockets, it is highly recommended that you remove Crash for your production deployments. Crash is in the crash.war file in tomcat/webapps.
Remove a Crash
1. Stop the serve by using the shutdown.sh command.
2. Delete the crash.war file.
3. Restart the server.
