Is the LDM system running? Check via the command "ps -ef | grep ldmd". If it 
is, then the file "ldmd.pid" in the top-level source-directory was somehow 
removed and the best thing to do is to replace it. Find the top-level LDM 
server in the output of the ps(1)) command: it will be the one whose parent PID 
is 1. Put the PID of the top-level LDM server in the file "ldmd.pid" in the LDM 
user's home-directory and retry the command "ldmadmin stop".

If, however, the LDM isn't running, the execute the command "ldmadmin clean" 
before trying to restart it.
