Here is an strace of trying to manually start the daemon (I'm not sure I can use strace useful in this way, but see the end of this bug report for more information). I realized afterwards that, at this stage, I forgot to manually remove the pid file, but I have left this strace here because I noticed that jabberd attempts to access /var/run/nscd/socket, but I did not have nscd installed on the test machine. I'm not sure if jabber requires nscd, but installing it didn't help. If nscd isn't important, then ignore this strace and look at the next one. # strace start-stop-daemon -b -c jabber:adm --start --pidfile /var/run/jabber/jabber.pid --exec /usr/sbin/jabberd
