Sorry, I thought repeating the bug report was a bit redundant.  But 
here you are:
Running on ~ppc

Bugzilla Bug 42835
xinetd-2.3.13 hangs with amanda 2.4.4-r3

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:

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