TSM - CPF414D

This weekend I received a message CPF414D while using TSM.  I do have a 
pmr open with TSM/IBM, but I thought I'd do a little searching on my own. 
Found nothing at ibm.com or at google.

Message . . . . :   Database busy or error occurred  
Cause . . . . . :   The library database was busy or failed with an error  
 
  during operations on library device TAPMLB01. QUSRSYS must be installed 
on 
  the system before using a media library device and the following files 
must
  be available in QUSRSYS: QATAMID, QLTAMID, QATACGY, QLTACGY, QATAFTR.  
Recovery  . . . :   See the previously listed messages to determine the  
  correct database error recovery action. Correct the problem and retry 
the 
  operation.  

I've been running TSM for awhile so it's not like the files weren't there.

'available'?  Wondered about that.  A library save was going on outside of 
TSM.  In the DSPLOG I see shortly before/after this message:
...
70 objects saved from library MGRRPLOBJ.
...
Database busy or error occurred
...
4 objects saved from library MGRSAVEGL.
...

But QUSRSYS is normally saved around 10:30 am to save files and is, thus, 
no where near the 00:54 time frame of this error.  Therefore I can see no 
cause for them to be not available.
