[gentoo-ppc-user] xinetd won't restart service after connect

[Bryn Hughes]

Hi everyone,

I have xinetd-2.3.13 installed on my gentoo-ppc system.  I'm trying to 
use amanda on this server (which I have used successfully on many other 
servers) but I seem to be having some trouble specifically with the 
amanda service.  The first time a backup process connects to the server 
the amanda service is started properly by xinetd.  From running xinetd 
-d (debug mode) I am able to see that 2 connections are made, the first 
one exits and xinetd resumes the service properly.  After the second 
connection exits however xinetd does NOT resume the amanda service.  
This means any future connections fail.  If you look at the log below 
you can see the first connection detach and xinetd resume the service.  
I can wait for any amount of time and xinetd never seems to resume 
after the second connection.  After the second connection xinetd starts 
using CPU time like crazy too even though it isn't doing anything.

Below is an example run of xinetd -d:
