This shouldn't happen and indicates that the O/S is lying about the number
of files that can be open simultaneously.  I'lll have a look at this when
I return from Scotland.

In the meantime, try one of the following:

    1.  Running multiple "pqact" processes, each with its own configuration-
        file that processes a subset of the data.

    2.  Adding the "close" option to some of the entries in the "pqact"
        configuration-file.

Steve Emmerson
