It doesn't dissapear, just is unwritable, and perhaps slowed down.  When I have been 
watching the logs as the process is run, I see authentication requests continuing, 
along with unresponcive child processes.  When the dump finishes there is a burst of 
radacct data/errors and then the radiusd failes and goes into it's unresponsve state.
