Thanks for the tip. This is the output I get
[root@localhost sbin]# cd /usr/sbin

In the debugger bacula-sd starts and appears to work normally (in that Bat
console can connect to it) although when I query the daemon status is says it
is stopped, as opposed to dead previously.
It turns out that if I add the "-s" command line option (for "Do not trap
signals") to the init.d daemon script then bacula-sd will start and function
correctly, though it then returns status of dead and cannot be stopped using
the script & has to be killed instead. I also get the syslog error messages
about libc when I query the status or try to stop the daemon.
I also built bacula-sd from 5.0.2 source, and got the same outcome as with the
FC14 package - which suggests it isn't a Fedora package build error. I haven't
tried building 5.0.3 and Fedora doesn't appear to have a package in
updates-testing or even rawhide yet.
Works for me again now, but any ideas what is going wrong?
