Maintenance
Challenger contains a number of tools for maintenance tasks. Most of them are found on the Actions tab. These tools are mostly useful if the Challenger server is used for development purposes.

Restarting
The most common remedy when unusual things happen is to restart the server with the Shutdown/Shut down Roxen action. This makes the server start fresh and reread all data from disk.

Cache / Flush caches
The Cache/Flush caches action allows the administrator to empty Challenger's built-in caches.

Maintenance
The Maintenance actions are tools for doing maintenance tasks.

`Check your Roxen configuration for problems ...`
  Performs several sanity checks of the configuration and proposes suitable adjustments when discovering problems.

`Clear Event Log`
  It is possible to clear all or specified types of events from the event log if it grows too large.

`Reload configuration from disk`
  Forces a reload of all configuration information from the configuration files. This works as an undo in case you have unsaved configuration changes you don't want to keep.
