The LDM log-file contained this

It looks like the crash left the .state file that pqact(1) uses
in a bad state (2008-04-09 is too long ago).  The pqact(1) process
then died:

I suggest trying the following:

1.  Stop the LDM (ldmadmin stop).

2.  Remove all the .state files (rm $HOME/etc/*.state)

3.  Start the ldm (ldmadmin start).

4.  Check the LDM log-file for errors.
