dbCaAddOutlink is normally called by either record or device support.
One of the arguments is the name of the field, within the
same record, that contains the data value. My guess
is that something is calling this with a field that
that has one of the types  DBF_INLINK,DBF_OUTLINK,DBF_FWDLINK,
or DBF_NOACCESS.

Do you have some locally developed record or device support?
I dont remember this being reported for any of the support
provided with epics base.

In 3.12 there is no easy way. But you can do the following:

If the database is in the .database format convert to .db format.
   a) Use dct to create a short form report
   b) use sf2db to create a .db format file
   c) use dbLoadRecords instead of dbLoad to load the database
Start eliminating records until you isolate the record causing the
error.

If you convert to 3.13 the problem will either go away
or else error messages identify the record and field that
are causing problems.

I think this means that the database is in the .database format,
i.e. a binary format. The .db formart is an ascii file which you
can easily edit.
