It sounds like your queue is getting corrupted for some unknown reason.  If
the queue is corrupt and you try to restart the ldm, it will not
work.  On you system, when you reboot, /etc/init.d/ldmd is set up
to delete and remake the queue.  If you want to avoid a reboot, 
just run:

ldmadmin delqueue
ldmadmin mkqueue
ldmadmin start

if it doesn't start after failing.

The next question is why is this happening and why did it start all of
a sudden.  I don't see that any of your ldm configuration files have 
been modified recently, so have there been any other changes made to 
the system?

If this happens again, check which program is dumping core.  In the
directory where the core file is, run:

file core

and part of the output is the program that created the core file.
Let us know which program has the problem.
