Hello,

It might be faster to resolve if we can do a quick google meet where you can 
share your screen.

But you may try:

Again kill any LDM processes as root user
Delete the ldmqueue (as root)
   ldmadmin delqueue

Then as awips user do a clean and re-create the queue:
ldmadmin clean
ldmadmin mkqueue

Then try to start ldm
service edex_ldm start

If that doesn't work (and if it hangs for more than a minute, go ahead and kill 
it), try "ldmadmin start" and see if it spits out an error

And possibly look at the permissions in:
/awips2/ldm
/awips2/ldm/var/queues
