Eric,

The LDM lockfile is a save guard so more than one person can't do
a critical command at the same time,  ie try to start the LDM. If a
critical command is in progress and it's terminated abnormally, ie CNTL C
then the lockfile is still in place.  To remove the lockfile, do

% ldmadmin clean

This removes the lockfile and the ldmd.pid file so now the critical
commands can proceed.
