Do you allocate the modellist array in the database process or in the
application process ? You should allocate the array in the process
that spawns the other one. And do this BEFORE the process is spawned.
This way both processes should be able to access the array. You can
than allocate all elements in the application process OR the database
process.

By saying that the modellist is NULL in the application process I guess
that you allocated the array in the database process. I think that this
is the problem.
