Description (Answer)
This is common error when one has huge model with lots of output frequencies. Avoidance is to use new xdb format (see PS***) that won't have this problem. In order to create xdb with new style, one needs to use following Nastran System Cell, as the very first line of the bdf file/input deck.
Nastran DBCFACT = 4

    Hi Don, Thanks for the quick reply. This is a large model running in MSC Nastran V2018.2. I am running a SOL 111 restart requesting a few  grid accelerations. The full message is pasted below (this is from a run where I included the Param,​DBCDIAG,4). I am getting this error when I request Acceleration output, I have output some CBUSH element forces from the same model and I do not get this error.
     
    Here is the error from the f06:
     MSC.XL      DATA BASE CONVERSION STARTED
      PARAMETER PATH QUALIFIERS RECOVERY
