I'm sorry to hear ldm is giving you trouble.  Can you try running the following
commands as the user awips:
 ldmadmin delqueue
 ldmadmin clean
 ldmadmin mkqueue
 sudo service edex_ldm start

What those commands do is delete and recreate your ldm queue, because from the 
log message you sent, it looks like it may have gotten corrupted.

Let me know if that works?
Thanks!
