After a day my idle Geronimo 3 server has already used over one cpu hour. This is a serious bug, which forbids using Geronimo on CPU-restricted machines (e.g. z/OS) and should be fixed.
Geronimo also could look if it runs under a JRE 7 and use the Watch Service API, so idle CPU usage could be zero. https://blogs.oracle.com/thejavatutorials/entry/watching_a_directory_for_changes Greetings, Juergen Jarek Gawor wrote > The server is periodically pooling the etc/ for new configuration > files and hotbundles/ directory for new bundle files.
