Yes, you use the kconfig utility to change the size of the file
table. Lots of this sort of thing are adjustable under A/UX
using kconfig - type "kconfig -va" to see the full list.

Specifically, to set the file table size to 300 (for example),
type

        kconfig -n /unix
        NFILE = 300
        ^D

You can also use += or -= to adjust the current value rather
than just replacing it.

This may not cure your problem however: if the problem is
per-process file table sizes then that isn't adjustable
(software which has only ever run on Suns may assume that you
can open 40+ files in a single process).

You should also check carefully to find out if your news feed
is ignoring attempts to limit it to a sensible number of
concurrent delivery attempts: if it wants to give you your
daily 8 megabytes as N thousand simultaneous transfers then
you'll have problems anyway!
