The OpenNMS Web User Interface Has Experienced an Error
The OpenNMS web UI has encountered an error that it does not know how to handle.
Possible causes could be that the database is not responding, the OpenNMS application has stopped or is not running, or there is an issue with the servlet container.
Please bring this message to the attention of the person responsible for maintaining OpenNMS for your organization, and have him or her check that OpenNMS, the external servlet container (if applicable), and the database are all running without errors.
