Check all outputs for errors as described in the Logging section. In the default configuration, log4j messages will be written to log/rmi/rmi_server.log. Under Windows running as a service standard error and standard output will be redirected to time stamped files in log/procrun. In a Linux install standard error and output will end up in nohup.out in the bin directory. Note that many cartridge functions are time consuming and currently all operations block and are applied in a first in, first out queue. If there are no obvious error causes it may be worth restarting the cartridge.
