When running Tomcat on unixes, the console output is usually redirected to the file named catalina.out. The name is configurable using an environment variable. Whatever is written to System.err/out will be caught into that file. That may include:
- Uncaught exceptions printed by java.lang.ThreadGroup.uncaughtException(..)
- Thread dumps, if you requested them via a system signal
