In the last week, I've seen LDM mysteriously die on one Linux box.  I checked
system messages, and saw a logged "segmentation violation" from rpc.ldmd.
The same process was running on another Linux box with no problems, though
it wasn't processing exactly the same data.  Since "rpc.ldmd" is setuid
ROOT, I didn't get a core dump.

You might check your messages file (probably /var/adm/messages or
/var/log/messages) to see if something similar is logged.
