libroxen-watchdog 1.0-10 (i386 binary) in ubuntu edgy

 This module is meant to "shut off" (in a similar way to the switch
 module) parts of the server's virtual filesystem if the server is
 experiencing overload conditions. Currently to determine the overload
 status the server uses the system's load average via the "uptime"
 command. If it exceeds a threshold, the request is denied with a
 "server overloaded" HTTP error message. Future versions could assume
 the role of a rough traffic shaper too. The module is also fairly
 simple, and can be easily customized to fit particular purposes.
