Description Bryn Hughes 2004-02-24 20:58:05 UTC 
Running on ~ppc

Symptoms:  run amcheck or any other amanda utilities which contact backup server.  First connection will be sucessful but any subsequent connections fail.  xinetd starts using CPU time after second connection and never dies.  Using /etc/init.d/xinetd to try and stop is not sucessful, only kill -9 will do.

xinetd -d gives this:

# xinetd -d

At this point xinetd is hung - {drain} never comes and xinetd will no longer accept connections on any service.
