Ken,

There are many things that could cause the LDM to just stop. Here's a
couple of things I would check:

- scan the ldmd.log for error messages
- remake the LDM queue
- make sure your disks don't periodically fill to capacity, check scour
- some other program interferring with the LDM, ie hogging the CPU
- put the LDM into verbose logging by in the LDM home dir:

% kill -USR2 `cat ldmd.pid`

- scan the ldmd.log for error messages  again

Read the ldmd man page for details about rotating LDM verbosity
